Write a loop that will iterate over a list of items and only output items which have letters inside of a string

Question

So this is my code in python:

names = ['John', ' ', 'Amanda', 5]
valid = []
for correct_names in names:
    if correct_names.isalpha():
        valid.append(correct_names)
print(valid)

but when I initialize it I am getting:
AttributeError: ‘int’ object has no attribute ‘isalpha’ I am planning to have an output of
['John', 'Amanda']

without using regular expressions as I am working my way up in learning python again.

Any suggestion is greatly appreciated. Thank you.

Answer 1

The requirement is for two restrictions: 1) its a string, 2) it has letters. Use isinstance for the first and search the string for an alpha for the second.

names = ['John', ' ', 'Amanda', 5]
valid = []
for correct_names in names:
    if isinstance(correct_names, str):
        for c in correct_names:
            if c.isalpha():
                valid.append(correct_names)
                break
print(valid)
