Python program to calculate the number of digits and letters in a string
Let us suppose that we have a string and we have to calculate the total number
of digits and letters present in the string.
For Example
Input −
s = “tutorialsP0int”
Output −
Letters: 13
Digits: 1
Explanation −
Total number of letters and digits present in the given string are 13 and 1.
Approach to Solve this Problem
To calculate the total number of letters and digits in the given string, we have to
first iterate over the whole string. If we get an alphabet, then we increment the
letter count; otherwise, if we extract a digit, then increment the digit count.
Take an input string.
While iterating over the whole string, if we find a digit, then increment the
count of digits; otherwise, if we find a letter, then increment the count of
letters.
Return the count of letters and digits as the output.
Example
str = "tutorialsP0int"
digit=letter=0
for ch in str:
if ch.isdigit():
digit=digit+1
elif ch.isalpha():
letter=letter+1
else:
pass
print("Letters:", letter)
print("Digits:", digit)Output
Running the above code will generate the output as follows −
Letters: 13
Digits: 1
