How to divide in python – Python Program to Divide a String in ‘N’ Equal Parts

How to divide in python: In the previous article, we have discussed Python Program to Check Evil Number or Not
Given a string and the task is to divide the given string into “N” equal parts.

Examples:

Example1:

Input:

Given string = "aaaabbbbccccddddeeee"

Output:

The given string after dividing into 5 equal halves:
aaaa
bbbb
cccc
dddd
eeee

Example2:

Input:

Given string = "hellobtechgeeks"

Output:

The given string cannot be divided into 4 equal halves

Program to Divide a String in ‘N’ Equal Parts

Below are the ways to divide the given string into “N” equal parts.

Method #1: Using For Loop (Static Input)

Approach:

  • Give the string as static input and store it in a variable.
  • Give the number say ‘n’ as static input and store it in another variable.
  • Calculate the len of the given string using the len() function and store it in another variable.
  • Check if the length of the string modulus given number is not equal to ‘0’ or not using the if conditional statement.
  • If the statement is true, print “The given string cannot be divided into n equal halves”.
  • Else loop from 0 to length of the string with the step size of given number ‘n’ using the for loop.
  • Slice from the iterator value to the iterator +n value using slicing and print them.
  • The Exit of the Program.

Below is the implementation:

# Give the string as static input and store it in a variable.
gvn_str = "aaaabbbbccccddddeeee"
# Give the number say 'n' as static input and store it in another variable.
num = 5
# Calculate the len of the given string using the len() function and store it
# in another variable.
len_str = len(gvn_str)
# Divide the length of the string by a given number and store it in another variable say 'k'.
k = len_str//num
# Check if the length of the string modulus given number is not equal to '0' or
# not using the if conditional statement.
if(len_str % num != 0):
    # If the statement is true, print "The given string cannot be divided into n equal halves".
    print("The given string cannot be divided into", num, "equal halves")
else:
  # Else loop from 0 to length of the string with the step size of the number 'k'
  # using the for loop.
    print("The given string after dividing into", num, "equal halves:")
    for i in range(0, len_str, k):
        # Slice from the iterator value to the iterator +n value using slicing and
        # print them.
        print(gvn_str[i:i+k])

Output:

The given string after dividing into 5 equal halves:
aaaa
bbbb
cccc
dddd
eeee

Method #2: Using For Loop (User Input)

Approach:

  • Give the string as user input using the input() function and store it in a variable.
  • Give the number say ‘n’ as static input and store it in another variable.
  • Calculate the len of the given string using the len() function and store it in another variable.
  • Divide the length of the string by a given number and store it in another variable say ‘k’.
  • Check if the length of the string modulus given number is not equal to ‘0’ or not using the if conditional statement.
  • If the statement is true, print “The given string cannot be divided into n equal halves”.
  • Else loop from 0 to length of the string with the step size of the number ‘k’ using the for loop.
  • Slice from the iterator value to the iterator +k value using slicing and print them.
  • The Exit of the Program.

Below is the implementation:

# Give the string as user input using the input() function and store it in a variable.
gvn_str = input("Enter some random string = ")
# Give the number say 'n' as user input using int(input()) and store it in another variable.
num = int(input("Enter some random number = "))
# Calculate the len of the given string using the len() function and store it
# in another variable.
len_str = len(gvn_str)
#Divide the length of the string by a given number and store it in another variable say 'k'.
k=len_str//num
# Check if the length of the string modulus given number is not equal to '0' or
# not using the if conditional statement.
if(len_str % num != 0):
    # If the statement is true, print "The given string cannot be divided into n equal halves".
    print("The given string cannot be divided into", num, "equal halves")
else:
  # Else loop from 0 to length of the string with the step size of the number 'k'
  # using the for loop.
    print("The given string after dividing into", num, "equal halves:")
    for i in range(0, len_str, k):
        # Slice from the iterator value to the iterator +n value using slicing and
        # print them.
        print(gvn_str[i:i+k])

Output:

Enter some random string = 1234567890
Enter some random number = 2
The given string after dividing into 2 equal halves:
12345
67890
