This error occurs when you try to call the remove()
method on a string to remove one or more characters. You can solve the error by calling the replace()
method on the string or by calling the remove()
method on a string. For example,
my_str = 'fruits' new_str = my_str.replace('s','')
This tutorial will go through the error in detail and how to solve it with code examples.

AttributeErrror: ‘str’ object has no attribute ‘remove’
AttributeError occurs in a Python program when we try to access an attribute (method or property) that does not exist for a particular object. The part “‘str’ object has no attribute ‘remove’” tells us that the string object we handle does not have the attribute remove()
.
remove()
is a list method that removes the first occurrence of the specified element.
We can check if an attribute exists for an object using the dir()
function. For example,
my_str = 'Python' print(type(my_str)) print('remove' in dir(my_str))
<class 'str'> False
We can see that remove()
is not in the list of attributes for the str
object.
Example
Let’s look at an example of trying to call the remove()
method on a string.
# Create string with unwanted characters my_str = 'ssfruits' # Attempt to remove the unwanted 's' at the start of the string new_str = my_str.remove('s') print(new_str)
Let’s run the code to see what happens:
--------------------------------------------------------------------------- AttributeError Traceback (most recent call last) Input In [3], in <cell line: 2>() 1 my_str = 'ssfruits' ----> 2 new_str = my_str.remove('s') 3 print(new_str) AttributeError: 'str' object has no attribute 'remove'
The error occurs because remove()
is not a string method in Python.
Solution
We can solve the error by calling the str.replace()
method that returns a copy of the string with the replaced characters. The syntax of the replace()
method is as follows:
string.replace(old_value, new_value, count)
old_value
: Required. The string to search fornew_value
: Required. The string to replaceold_value
withcount
: Optional. A number specifying how many occurrences ofold_value
to replace. Default is all occurrences.
We can remove a character by setting the new_value
to ''
. Let’s remove the first two occurrences of the 's'
character from the string. We want to keep the third occurrence of 's'
, so we will set count
to 2
my_str = 'ssfruits' new_str = my_str.replace('s', '', 2) print(new_str)
Let’s run the code to get the result:
fruits
List Remove Method
If we want to remove the first occurrence of an element from a list, we can use the remove()
method. For example,
my_lst = ['whale', 'lion', 'zebra', 'owl', 'platypus'] try: my_lst.remove('lion') except ValueError: print('Item not in list') print(my_lst)
['whale', 'zebra', 'owl', 'platypus']
