Python Concatenate String and Function

Question

Is there a way in Python to cat a string and a function?

For example

def myFunction():
    a=(str(local_time[0]))
    return a

b="MyFunction"+myFunction

I get an error that I cannot concatenate a 'str' and 'function' object.

Did you want to use the return value of myFunction() here?
If you are trying to just use the name, you could use __name__ with myFunction and then concatenate them. (stackoverflow.com/a/255297/758446)

There are two possibilities:

If you are looking for the return value of myfunction, then:

print 'function: ' + myfunction()

If you are looking for the name of myfunction then:

print 'function: ' + myfunction.__name__

	I want to cll the function like b="MyFunction"+myFunction(), sorry, I missed the () above. I am used to C++. I want to run the function in the statement declaring b, is that possible? I can do it if I run myFunction() outside of declaring b but I want to do it during that declaration, is it possible in python? – user2295959 Apr 19 at 12:29
	Calling the function will return a string. See the code here: ideone.com/UCUMgO. – segfolt Apr 19 at 12:50

You need to call your function so that it actually returns the value you are looking for:

b="MyFunction"+myFunction()

	When I do that I ger the error that I cannot concatenate a 'str' and 'function' object. – user2295959 Apr 19 at 12:31
	@user2295959, it worked for me... Did you notice the parenthesis? – mjgpy3 Apr 19 at 12:48
