How do you use the output of one function to another function?

Call a function within a second function call to pass the output into the second function.

1. def add_1(a):
2. return(a + 1)
3. def add_2(c):
4. return(c + 2)
5. output = add_1(add_2(0)) Pass `0` to `add_2` and pass result to `add_1`
6. print(output)

How do you return a value from one function to another in python?

You have to explicitly pass the return value in to the second function. The function returns a value, but it doesn’t create the symbol in any sort of global namespace as your code assumes. You have to actually capture the return value in the calling scope and then use it for subsequent operations.
