Question

Given a string, such as x = ‘itm330’, write a Python program to count the number of digits and the number of letters in it. For example, in ‘itm330’, there are 3 letters and 3 digits.

Hint: Very similar to page 11 on the slides. To check if a character c is a digit, use c.isdigit(). If c is a digit, c.isdigit() will be a True.

Answer 1

Python code for the problem is provided below, please comment if any doubts:

Note: The indentation may lost when you copy the below code, so refer the screenshot provided at the end to reconstruct the indentation if any such problem occurs

Python Code:

#set the string
x='itm330'

#decalare the counts
numLetters=0
numDigits=0

#The for loop to count the digits and characters
for c in x:
    #if character is a digit
    if c.isdigit():
        #Update the digits count
        numDigits=numDigits+1
    #if character is a letter
    elif c.isalpha():
        #Update the letter count
        numLetters=numLetters+1
    else:
        pass

#display the result
print("Letters count: ", numLetters)
print("Digits count: ", numDigits)

Output:
