In the previous article, we have discussed Python Program to Replace a Word with Asterisks in a Sentence
Given a number and the task is to count the number of odd and even digits in a given number.
Examples:
Example1:
Input:
Given Number = 1237891
Output:
The count of even digits in a given number{ 1237891 } = 2
The count of odd digits in a given number{ 1237891 } = 5Example2:
Input:
Given Number = 78342186453
Output:
The count of even digits in a given number{ 78342186453 } = 6
The count of odd digits in a given number{ 78342186453 } = 5Program to Count the Number of Odd and Even Digits in Python
Below are the ways to count the number of odd and even digits in a given number :
Method #1: Using For Loop (Static Input)
Approach:
- Give the number as static input and store it in a variable.
- Convert the given number to a string using the str() function and store it in another variable.
- Create a list of digits say “digtslst” using map(),list(),int functions.
- Store it in another variable.
- Take a variable say “evn_count” and initialize it with 0.
- Take another variable say “od_count” and initialize it with 0.
- Loop in the above list of digits until the length of the “digtslst” using the for loop.
- Check if the iterator value of “digtslst” is even or not using the if conditional statement.
- If the statement is true, increment the count value of “evn_count” by 1.
- If the statement is false, increment the count value of “od_count” by 1.
- Print “evn_count” to get the count of even digits in a given number.
- Print “od_count“ to get the count of odd digits 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.
numb = 1237891
# Convert the given number to string using the str() function.
stringnum = str(numb)
# Create a list of digits say "digtslst" using map(),list(),int functions.
digtslst = list(map(int, stringnum))
# Take a variable say "evn_count" and initialize it with 0.
evn_count = 0
# Take another variable say "od_count" and initialize it with 0.
od_count = 0
# Loop in the above list of digits until the length of the "digtslst" using the for loop.
for itr in range(len(digtslst)):
# Check if the iterator value of "digtslst" is even or not using
# the if conditional statement.
if(digtslst[itr] % 2 == 0):
# If the statement is true, increment the count value of "evn_count" by 1.
evn_count += 1
else:
# If the statement is false, increment the count value of "od_count" by 1.
od_count += 1
# Print "evn_count" to get the count of even digits in a given number.
print("The count of even digits in a given number{", numb, "} =", evn_count)
# Print "od_count" to get the count of odd digits in a given number.
print("The count of odd digits in a given number{", numb, "} =", od_count)
Output:
The count of even digits in a given number{ 1237891 } = 2
The count of odd digits in a given number{ 1237891 } = 5Method #2: Using For loop (User Input)
Approach:
- Give the number as user input using the int(input()) function and store it in a variable.
- Convert the given number to string using the str() function.
- Create a list of digits say “digtslst” using map(),list(),int functions.
- Take a variable say “evn_count” and initialize it with 0.
- Take another variable say “od_count” and initialize it with 0.
- Loop in the above list of digits until the length of the “digtslst” using the for loop.
- Check if the iterator value of “digtslst” is even or not using the if conditional statement.
- If the statement is true, increment the count value of “evn_count” by 1.
- If the statement is false, increment the count value of “od_count” by 1.
- Print “evn_count” to get the count of even digits in a given number.
- Print “od_count“ to get the count of odd digits in a given number.
- The Exit of the Program.
Below is the implementation:
# Give the number as user input using the int(input()) function and
# store it in a variable.
numb = int(input("Enter some random number = "))
# Convert the given number to string using the str() function.
stringnum = str(numb)
# Create a list of digits say "digtslst" using map(),list(),int functions.
digtslst = list(map(int, stringnum))
# Take a variable say "evn_count" and initialize it with 0.
evn_count = 0
# Take another variable say "od_count" and initialize it with 0.
od_count = 0
# Loop in the above list of digits until the length of the "digtslst" using the for loop.
for itr in range(len(digtslst)):
# Check if the iterator value of "digtslst" is even or not using
# the if conditional statement.
if(digtslst[itr] % 2 == 0):
# If the statement is true, increment the count value of "evn_count" by 1.
evn_count += 1
else:
# If the statement is false, increment the count value of "od_count" by 1.
od_count += 1
# Print "evn_count" to get the count of even digits in a given number.
print("The count of even digits in a given number{", numb, "} =", evn_count)
# Print "od_count" to get the count of odd digits in a given number.
print("The count of odd digits in a given number{", numb, "} =", od_count)
Output:
Enter some random number = 78342186453
The count of even digits in a given number{ 78342186453 } = 6
The count of odd digits in a given number{ 78342186453 } = 5Explore more instances related to python concepts from Python Programming Examples Guide and get promoted from beginner to professional programmer level in Python Programming Language.
