AttributeError: 'list' object has no attribute 'endswith'

AttributeError: 'list' object has no attribute 'endswith' #

The Python "AttributeError: 'list' object has no attribute 'endswith'" occurs when we call the endswith() method on a list instead of a string. To solve the error, call endswith() on a string, e.g. by accessing the list at a specific index or by iterating over the list.

Here is an example of how the error occurs.

Copied!
my_list = ['google.com', 'example.com', 'example...']

# ⛔️ AttributeError: 'list' object has no attribute 'endswith'
if my_list.endswith('.com'):
    print('success')

We created a list with 3 elements and tried to call the endswith() method on the list which caused the error.

One way to solve the error is to access the list at a specific index before calling endswith().

Copied!
my_list = ['google.com', 'example.com', 'example...']

if my_list[0].endswith('.com'):
    print('success')

We accessed the list element at index 0 and called the endswith() method on the string.

If you need to call the endswith() method on each string in a list, use a for loop.

Copied!
my_list = ['google.com', 'example.com', 'example...']

for word in my_list:
    if word.endswith('.com'):
        print('string ends with .com')

We used a for loop to iterate over the list and called the endswith() method on each string.

The str.endswith method returns True if the string ends with the provided suffix, otherwise the method returns False.

To solve the error, you either have to correct the assignment of the variable and make sure to call endswith() on a string, or call endswith() on an element in the list that is of type string.

You can either access the list at a specific index, e.g. my_list[0] or use a for loop to iterate over the list if you have to call endswith() on each element.

You can view all the attributes an object has by using the dir() function.

Copied!
my_list = ['a', 'b', 'c']

# 👉️ [... 'append', 'clear', 'copy', 'count', 'extend', 'index',
#  'insert', 'pop', 'remove', 'reverse', 'sort' ...]
print(dir(my_list))

If you pass a class to the dir() function, it returns a list of names of the class's attributes, and recursively of the attributes of its bases.

If you try to access any attribute that is not in this list, you would get the "AttributeError: list object has no attribute" error.

Since endswith() is not a method implemented by lists, the error is caused.

The Python "AttributeError: 'list' object has no attribute 'endswith'" occurs when we call the endswith() method on a list instead of a string. To solve the error, call endswith() on a string, e.g. by accessing the list at a specific index or by iterating over the list.
