AttributeError: ‘str’ object has no attribute ‘append’

In this guide, we talk about AttributeError: 'str' object has no attribute 'append' and why it is raised. here use The append() method does not work if you want to add a string to another string because append() is only supported by list items. Python returns an error stating AttributeError: ‘str’ object has no attribute ‘append’.

The AttributeError: ‘str’ object has no attribute ‘append’ error is raised when developers use append() instead of the concatenation operator. You forget to add value to a string instead of a list.

Example

names = ["Ram", "Shyam", "Joi", "Raju"]
s_names = ""

for n in names:
    s_names.append(n)
​
Traceback (most recent call last):
File "", line 2, in
AttributeError: 'str' object has no attribute 'append'

The Solution

names = ["Ram", "Shyam", "Joi", "Raju"]
s_names = []

for value in names:
    s_names.append(value)
print("The students names : {}".format(s_names))

Output : The students names : ['Ram', 'Shyam', 'Joi', 'Raju']
