In the previous article, we have discussed Python Program for Comma-separated String to Tuple
Given a number, and the task is to find the greatest digit in a given number.
Example: Let the number is 149.
The greatest digit in a given number is ‘9’
Examples:
Example1:
Input:
Given number = 639
Output:
The maximum digit in given number { 639 } = 9
Example2:
Input:
Given number = 247
Output:
The maximum digit in given number { 247 } = 7

Program to Find the Greatest Digit in a Number.
Below are the ways to find the greatest digit in a given number.
Method #1: Using list() Function (Static input)
Approach:
- Give the number as static input and store it in a variable.
- Convert the given number into the string using the str() function and store it in another variable.
- Convert the above-obtained string number into a list of digits using the built-in list() method and store it in another variable.
- Find the maximum list of digits using the built-in max() function and store it in another variable.
- Print the greatest digit in a given number.
- The Exit of the program.
Below is the implementation:
# Give the number as static input and store it in a variable.
gvn_num = 154
# Convert the given number into string using str() function and
# store it in another variable.
str_numbr = str(gvn_num)
# Convert the above obtained string number into list of digits using bulit-in list()
# method and store it in another variable.
lst = list(str_numbr)
# Find the maximum of list of digits using bulit-in max() function
# and store it in another variable.
maxim_digit = max(lst)
# Print the greatest digit in a given number.
print("The maximum digit in given number {", gvn_num, "} = ", maxim_digit)
Output:
The maximum digit in given number { 154 } = 5
Method #2: Using list() Function (User input)
Approach:
- Give the number as user input using the int(input()) function and store it in a variable.
- Convert the given number into the string using the str() function and store it in another variable.
- Convert the above-obtained string number into a list of digits using the built-in list() method and store it in another variable.
- Find the maximum list of digits using the built-in max() function and store it in another variable.
- Print the greatest digit in a given number.
- The Exit of the program.
Below is the implementation:
#Give the number as user input using int(input()) and store it in a variable.
gvn_num = int(input("Enter some random number = "))
# Convert the given number into string using str() function and
# store it in another variable.
str_numbr = str(gvn_num)
# Convert the above obtained string number into list of digits using bulit-in list()
# method and store it in another variable.
lst = list(str_numbr)
# Find the maximum of list of digits using bulit-in max() function
# and store it in another variable.
maxim_digit = max(lst)
# Print the greatest digit in a given number.
print("The maximum digit in given number {", gvn_num, "} = ", maxim_digit)
Output:
Enter some random number = 183
The maximum digit in given number { 183 } = 8
