This example demonstrates how to use the any and isalpha functions to check if a character string contains a letter from the alphabet.Let’s check our first character string my_string1:print(any(c.isalpha() for c in my_string1)) # Check if letters are contained in string # True...
[GeeksforGeeks - Check if a string contains all unique characters](
we have to call it on the string that’ll be used for joining. In this case, we’re using a string with a space in it. The method receives a list of strings and returns one string with each of the strings joined by the initial string. Let’s check its functionality with...
