Hi guys, i just want to ask if how can i count the alphanumeric of a given string.

Answer 1

Prepare the variable for storing number of alphanumeric, and initialize its value by zero.

Iterate through the string, check whether .isalnum() method returns true for the i-th character.

If <character>.isalnum() returns true, increment the alphanumeric counter variable.

Are you trying to get the ordinals (numbers) of each letter in a string

txt = input()
print([ord(i) for i in txt])
