Question

What is the result of the following segment of code:

data = ['Mike', '345', 'HELLO', 'Number125']
for index in range(len(data)):
-> print(data[index].isalpha())

Answer 1

The code checks if each element of the list is composed solely of letters and prints True or False for each element. 'Mike' and 'HELLO' result in True, while '345' and 'Number125' result in False.

Step-by-step explanation:

The provided segment of code is a Python script that checks each element in the list data to determine if it consists entirely of alphabetic characters. The isalpha() method returns True if all characters in the string are alphabetic and there is at least one character; otherwise, it returns False. The loop iterates over the range of indices that correspond to the positions of the elements in the list and prints the result of the isalpha() check for each element.

Here's the expected output:

• True (because 'Mike' is all letters)
• False (because '345' contains digits)
• True (because 'HELLO' is all letters, even though they're uppercase)
• False (because 'Number125' contains both letters and digits)
