Python Program to Count Number of Lowercase Characters in a String

This is a Python Program to count number of lowercase characters in a string.

The program takes a string and counts number of lowercase characters in a string.

1. Take a string from the user and store it in a variable.
2. Initialize a count variable to 0.
3. Use a for loop to traverse through the characters in the string and increment the count variable each time a lowercase character is encountered.
4. Print the total count of the variable.
5. Exit.

Here is source code of the Python Program to count number of lowercase characters in a string. The program output is also shown below.

string=raw_input("Enter string:")
count=0
for i in string:
      if(i.islower()):
            count=count+1
print("The number of lowercase characters is:")
print(count)

1. User must enter a string and store it in a variable.
2. The count variable is initialized to zero.
3. The for loop is used to traverse through the characters in the string.
4. The count is incremented each time a lowercase character is encountered.
5. The total count of lowercase characters in the string is printed.

 
Case 1:
Enter string:Hello
The number of lowercase characters is:
4
 
Case 2:
