Python：如何使用for循环调用所有函数？

Question

I want to use the f_i function like this:

for i in range (9):
    f_i(y)=c

But I don't know how to use the value of i to call all my ten functions. So what should I do?

Answer 1

Make a list containing the functions and use each function by using loop as follows.

def f1(x):
    return x

def f2(x):
    return x * 2

def f3(x):
    return x * 3

function_list = [f1, f2, f3]
for f in function_list:
    print(f(1))

Answer 2

Assume functions is defined/imported into the current file.

locals().get() is the thing that you want

for i in range (9):
    func = locals().get("f_{}".format(i))
    func(y)
