Before you mark it as duplicate, please see this python code and results

X=5

print("X value is:"+str(X))

Traceback (most recent call last): File "", line 1, in print("X value is:"+str(X)) TypeError: 'str' object is not callable*

As far as I know, str should work here because I am simply printing the value of variable here. Any clues?

Answer 1

The problem is str function must have been overloaded.

Input:

X=5
print("X value is:"+str(X))

Output: X value is:5

Input:

X=5
str = "98897"
print("X value is:"+str(X))

Output: TypeError Traceback (most recent call last) in () ----> 1 print("X value is:"+str(X))

TypeError: 'str' object is not callable
