I got this warning from an incomplete method check:

if hasattr(w, 'to_json'):
    return w.to_json()
             ######### warning, 'str' object is not callable

It assumed w.to_json was a string. The solution was to add a callable() check:

if hasattr(w, 'to_json') and callable(w.to_json):

Then the warning went away.

FWIW I just hit this on a slightly different use case   I scoured and scoured my code looking for where I might ve used a  str  variable  but could not find it  I started to suspect that maybe one of the modules I imported was the culprit    but alas  it was a missing     character in a formatted print statement  Here s an example  x 5 y 6 print  quot x as a string is   s   y as a string is   s quot   str x    str y      This will result in the output     TypeError   str  object is not callable  The correction is  x 5 y 6 print  quot x as a string is   s   y as a string is   s quot     str x    str y      Resulting in our expected output  x as a string is  5  y as a string is  6

It is important to note  in case you came here by Google  that  TypeError   str  object is not callable  means only that a variable that was declared as String-type earlier is attempted to be used as a function  e g  by adding parantheses in the end    You can get the exact same error message also  if you use any other built-in method as variable name

I had yet another issue with the same error   Turns out I had created a property on a model  but was stupidly calling that property with parentheses    Hope this helps someone

Another case of this  Messing with the   repr   function of an object where a format   call fails non-transparently   In our case  we used a  property decorator on the   repr   and passed that object to a format     The  property decorator causes the   repr   object to be turned into a string  which then results in the str object is not callable error

Whenever that happens  just issue the following   it was also posted above    gt  gt  gt  del str   That should fix it

I had the same error  In my case wasn t because of a variable named str  But because I named a function with a str parameter and the variable the same  same name   same name var name  str   I run it in a loop  The first time it run ok  The second time I got this error  Renaming the variable to a name different from the function name fixed this  So I think it s because Python once associate a function name in a scope  the second time tries to associate the left part  same name    as a call to the function and detects that the str parameter is not present  so it s missing  then it throws that error

In my case  I had a Class with a method in it  The method did not have  self  as the first parameter and the error was being thrown when I made a call to the method  Once I added  self   to the method s parameter list  it was fine

An issue I just had was accidentally calling a string   Foo    Bar  if bar else  Baz     You can concatenate string by just putting them next to each other like so    Foo   Bar    however because of the open brace in the first example it thought I was trying to call  Foo

Check your input parameters  and make sure you don t have one named type  If so then you will have a clash and get this error

This is the problem   global str  str   str mar    You are redefining what str   means  str is the built-in Python name of the string type  and you don t want to change it    Use a different name for the local variable  and remove the global statement

While not in your code  another hard-to-spot error is when the   character is missing in an attempt of string formatting    foo  s bar  s coffee   blah   asdf     but it should be    foo  s bar  s coffee    blah   asdf     The missing   would result in the same TypeError   str  object is not callable

In my case I had a class that had a method and a string property of the same name  I was trying to call the method but was getting the string property

it is recommended not to use str int list etc   as variable names  even though python will allow it  this is because it might create such accidents when trying to access reserved keywords that are named the same
