In general, you can tell whether something is callable or not with the built-in function callable.

1 import math2 3 x=14 y=fibs_compute5 print(callable(x))6 print(callable(y))

 

定义函数，求斐波那契数列

1 import math 2  3 def fibs_compute(number): 4     fibs=[0,1] 5     for i in range(int(number)-2): 6         fibs.append(fibs[-1]+fibs[-2]) 7     return(fibs) 8      9 num=input("How many numbers do you want?")10 print("Here is:",fibs_compute(num))    11

 

The variables you write after your function name in def statements are often called the formal parameters of the function. 

The values you supply when you call the function are called the actual parameters, or arguments.
