## 1) Number Pattern – 1

### Method #1: Using For loop (Static Input)

Approach:

• Give the number of rows as static input and store it in a variable.
• Loop from 1 to the number of rows using For Loop.
• Loop from 1 to iterator value of the parent For loop using another For loop(Inner For Loop).
• Print the iterator value of the inner For loop.
• Print the Newline character after the end of the inner loop.
• The Exit of the Program.

Below is the implementation:

# Give the number of rows as static input and store it in a variable.
numbOfRows = 8
# Loop from 1 to the number of rows using For Loop.
for m in range(1, numbOfRows+1):
# Loop from 1 to iterator value of the parent For loop
# using another For loop(Inner For Loop).
for n in range(1, m+1):
# Print the iterator value of the inner For loop.
print(n, end=' ')
# Print the Newline character after the end of the inner loop.
print()

Output:

1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4 5 6
1 2 3 4 5 6 7

### Method #2: Using For loop (User Input)

Approach:

• Give the number of rows as user input using int(input()) and store it in a variable.
• Loop from 1 to the number of rows using For Loop.
• Loop from 1 to iterator value of the parent For loop using another For loop(Inner For Loop).
• Print the iterator value of the inner For loop.
• Print the Newline character after the end of the inner loop.
• The Exit of the Program.

Below is the implementation:

# Give the number of rows as user input using int(input()) and store it in a variable.
numbOfRows = int(input('Enter some random number of rows = '))
# Loop from 1 to the number of rows using For Loop.
for m in range(1, numbOfRows+1):
# Loop from 1 to iterator value of the parent For loop
# using another For loop(Inner For Loop).

### Method #1: Using For loop (Static Input)

Approach:

• Give the number of rows as static input and store it in a variable.
• Loop from the 1 to the number of rows using For loop.
• Loop from 1 to first loop iterator value using another Nested For loop.
• Print Two spaces.
• Loop from the first loop iterator value to the number of rows(included) using Another For loop.
• Print the iterator value of the inner For loop.
• Print the newline character after ending of inner For loop.
• Loop from the number of rows -1 to 1(included) in decreasing order using For loop.
• Loop from 1 to first loop iterator value using another Nested For loop.
• Print Two spaces.
• Loop from the first loop iterator value to the number of rows(included) using Another For loop.
• Print the iterator value of the inner For loop.
• Print the newline character after ending of inner For loop.
• The Exit of the program.

Below is the implementation:

# Give the number of rows as static input and store it in a variable.
numbOfRows = 8
# Loop from 1 to the number of rows using For loop.
for m in range(1, numbOfRows+1):
# Loop from 1 to first loop iterator value using another Nested For loop.
for n in range(1, m):
# Print Two spaces.
print(' ', end=' ')
# Loop from the first loop iterator value to the number of rows(included)
# using Another For loop.
for n in range(m, numbOfRows+1):
print(n, end=' ')

# Print the newline character after ending of inner For loop.
print()

# Loop from the number of rows -1 to 1(included) in decreasing order using For loop.

### Method #1: Using For loop (Static Input)

Approach:

• Give the number of rows as static input and store it in a variable.
• Take a variable and initialize it with 1 say sampNumber.
• Loop from 1 to the number of rows of the triangle using For loop.
• Using another For loop, loop from 1 to the parent loop iterator value (Nested For loop).
• Inside the inner for loop print the sampNumber with a space character.
• Increase the value of sampNum by 1.
• Print the Newline Character after the end of the inner for loop.
• The Exit of the program.

Below is the implementation:

# Give the number of rows of the triangle as static input and store it in a variable.
numbOfRows = 4
# Take a variable and initialize it with 1 say sampNumber.
sampNumber = 1
# Loop from 1 to the number of rows of the triangle using For loop.
for m in range(1, numbOfRows+1):
# Using another For loop, loop from 1 to the parent loop iterator value (Nested For loop).
for n in range(1, m+1):
# Inside the inner for loop print the sampNumber with a space character.
print(sampNumber, end=' ')
# Increase the value of sampNumber by 1.
sampNumber = sampNumber+1
# Print the Newline Character after the end of the inner for loop.
print()

Output:

### Method #2: Using For loop (User Input)

Approach:

• Give the number of rows as user input using int(input()) and store it in a variable.
• Take a variable and initialize it with 1 say sampNumber.
• Loop from 1 to the number of rows of the triangle using For loop.
• Using another For loop, loop from 1 to the parent loop iterator value (Nested For loop).
• Inside the inner for loop print the sampNumber with a space character.
• Increase the value of sampNum by 1.
• Print the Newline Character after the end of the inner for loop.
• The Exit of the program.

Below is the implementation:

# Give the number of rows as user input using int(input()) and store it in a variable.
numbOfRows = int(input('Enter some random number of rows = '))
# Take a variable and initialize it with 1 say sampNumber.
sampNumber = 1
# Loop from 1 to the number of rows of the triangle using For loop.
for m in range(1, numbOfRows+1):
# Using another For loop, loop from 1 to the parent loop iterator value (Nested For loop).
for n in range(1, m+1):
# Inside the inner for loop print the sampNumber with a space character.
print(sampNumber, end=' ')
# Increase the value of sampNumberby 1.

# Print the Newline character after the end of the inner loop.
print()

Output:

Enter some random number of rows = 8
1 2 3 4 5 6 7 8
2 3 4 5 6 7 8 1
3 4 5 6 7 8 2 1
4 5 6 7 8 3 2 1
5 6 7 8 4 3 2 1
6 7 8 5 4 3 2 1
7 8 6 5 4 3 2 1
8 7 6 5 4 3 2 1

## 25) Number Pattern – 25

### Method #1: Using For loop (Static Input)

Approach:

• Give the number of rows as static input and store it in a variable.
• Loop from 1 to the number of rows using For loop.
• Loop from the number of rows to the iterator value of the parent For loop using another For loop(Inner For loop).
• Print the space character.
• Loop from 1 to first loop iterator value using another Nested For loop.
• Print the inner loop iterator value.
• Print the newline character after ending of inner For loop.
• The Exit of the Program.

Below is the implementation:

# Give the number of rows as static input and store it in a variable.
numbOfRows = 9
# Loop from 1 to the number of rows using For Loop.
for m in range(1, numbOfRows+1):
# Loop from the number of rows to the iterator value of the parent
# For loop using another For loop(Inner For loop).
for n in range(numbOfRows, m, -1):
# Print the space character.
print(end=' ')
# Loop from 1 to first loop iterator value using another Nested For loop.
for n in range(1, m+1):
# Print the inner loop iterator value.
print(n, end=' ')

# Print the Newline character after the end of the inner loop.
print()

Output:

1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4 5 6
1 2 3 4 5 6 7
1 2 3 4 5 6 7 8
1 2 3 4 5 6 7 8 9

### Method #2: Using For loop (User Input)

Approach:

• Give the number of rows as user input using int(input()) and store it in a variable.
• Loop from 1 to the number of rows using For loop.
• Loop from the number of rows to the iterator value of the parent For loop using another For loop(Inner For loop).
• Print the space character.
• Loop from 1 to first loop iterator value using another Nested For loop.
• Print the inner loop iterator value.
• Print the newline character after ending of inner For loop.
• The Exit of the Program.

Below is the implementation:

# Give the number of rows as user input using int(input()) and store it in a variable.
numbOfRows = int(input('Enter some random number of rows = '))
# Loop from 1 to the number of rows using For Loop.
for m in range(1, numbOfRows+1):
# Loop from the number of rows to the iterator value of the parent
# For loop using another For loop(Inner For loop).
for n in range(numbOfRows, m, -1):
# Print the space character.
print(end=' ')
# Loop from 1 to first loop iterator value using another Nested For loop.
for n in range(1, m+1):
# Print the inner loop iterator value.
print(n, end=' ')

# Print the Newline character after the end of the inner loop.
print()

Output:

Enter some random number of rows = 13

1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4 5 6
1 2 3 4 5 6 7
1 2 3 4 5 6 7 8
1 2 3 4 5 6 7 8 9
1 2 3 4 5 6 7 8 9 10
1 2 3 4 5 6 7 8 9 10 11
1 2 3 4 5 6 7 8 9 10 11 12
1 2 3 4 5 6 7 8 9 10 11 12 13
