Python: AttributeError: 'list' object has no attribute 'join'

Current post is on how to recover from AttributeError: 'list' object has no attribute 'join'.


Started working on python and got struck in 'JOIN' function?

Got the "AttributeError: 'list' object has no attribute 'join' " error when trying to JOIN list in Python?

Just change the list and argument place.

Reason is we are wired to think like  object.some_function arguments but here its like argument.some_function object(s)


List JOIN in Python:


mypythonlist = ['ListElement1', 'ListElement2']
mypytonlist.join('-')   #Incorrect Usage which gave the AttributeError

'-'.join(mypythonlist)  #Correct Usage

# It will return 'ListElement1-ListElement2'

For detailed information refer to 'JOIN' function post

Hope this post saved your time.


Appreciate your feedback via comments. Thanks.
