AttributeError: ‘str’ object has no attribute ‘pop’ in Python

If you are in trouble with the error “AttributeError: ‘str’ object has no attribute ‘pop'” in Python, read this article carefully. We are about to show you the root of the problem and give you a few methods to deal with the error. Let’s move on. 

The reason for AttributeError: ‘str’ object has no attribute ‘pop’ in Python

The AttributeError: ‘str’ object has no attribute ‘pop’ error is raised when you try to call the pop() method on a string object in Python. The pop() method is not a valid method for strings, as it is only available for list objects.

Here is an example of code that would raise this error:

Code:

text = "Welcome to Learn Share IT"
text.pop() # Error raise in this line

Result:

AttributeError Traceback (most recent call last)
 in <module>
----> 2 text.pop() # Error raise in this line
AttributeError: 'str' object has no attribute 'pop'

Solution to AttributeError: ‘str’ object has no attribute ‘pop’

To fix this error, you can use a list object instead of a string or a different method available for strings, such as slice() or replace().

Convert the string into a list

You must first transform the string into a list to call the pop() attribute without error. To make the string become a list, use the split() function with the delimiter as the single white space. For example:

Code:

text = "Welcome to Learn Share IT"
print("The original string is:", text)
 
# Split the string
text = text.split(" ")
 
# Pop the element at the index 3
text.pop(3)
 
# Merge the string
text = " ".join(text)
print("The new string is:", text)

Result:

The original string is: Welcome to Learn Share IT
The new string is: Welcome to Learn IT

Slice the string

The “slice” technique returns a substring from the original string based on the defined interval in the function. For example, if you want to remove the last character from a string.

Code:

text = "Welcome to Learn Share IT"
print("The original string is:", text)
 
# Remove the last character
text = text[:-1]
print("The new string is:", text)

Result:

The original string is: Welcome to Learn Share IT
The new string is: Welcome to Learn Share I

Use the replace() method

Alternatively, you can use the replace() method to replace the last character with an empty string:

Code:

text = "Welcome to Learn Share IT"
print("The original string is:", text)
 
# Replace the last character with an empty character
text = text.replace(text[-1], "")
print("The new string is:", text)

Result:

The original string is: Welcome to Learn Share IT
The new string is: Welcome to Learn Share I

Summary

In summary, the error “AttributeError: ‘str’ object has no attribute ‘pop'” occurs when you apply the pop() attribute to a string, which is unavailable to the string type. To get rid of the error, you can create a list from the string and then apply the pop() attribute; or use the slice technique or the replace() method to remove the target characters.
