将 Python 函数脚本导入另一个 Python 文件？

Question

I have this python assignment where I need to do the following: You will create a file myFunctions.py, where you will define/write the functions below:

min(list) # returns min of a list max(list) # returns max of a list avg(list) # returns average of a list sum(list) # returns sum of a list abs(num) # returns absolute value of num find(key,list)# returns true if key value is found in a list isEven(number) # returns true/false if number is even You will import myFunctions.py into a file testFunctions.py, where you will call/test each of the above functions.

So far, here's what I've got: myFunctions.py:

from random import randint

x = randint(5,10)
aList = []
for i in range(0, x, 1):
    number = randint(1,7)
    aList.append(number)
    print(number, end=', ')

def min(aList):
    return min(aList)

def max(aList):
    return max(aList)

sum = 0
 def avg(aList):
sum = 0
for i in range(0,len(aList)):
    sum += aList
    return sum / len(aList)
def sum(aList):
    while True:
        return sum(aList)
        break
def abs(aList):
    return abs(aList[1])

def find(aList):
    x = aList.find()
    return x

def isEven(n):
    if n % 2 == 0:
        return True
    else:
        return False

testFunctions.py:

import myFunctions
from myFunctions import max

from random import randint

x = randint(5,10)
aList = []
for i in range(0, x, 1):
    number = randint(1,7)
    aList.append(number)
    print(number, end=', ')

myFunctions.max(aList)

I'm stuck on the parameters of each function and how to use them in the other python file.Any tips?

Answer 1

I'm not entirely sure what you are asking, but if you want to access aList from testFunctions , you can do so as myFunctions.aList .

However, I think you are confusing the aList in the function definition ( def max(aList):... ) with the aList in testFunctions . You named them the same, but they are different (but related) things.

When you call myFunctions.max(aList) in testFunctions it is taking aList that you made directly above it in the same file and passing it to the function max . Within max whatever list is the input is given a local variable name aList regardless of the name of the variable when you called max(aList) . If you made a bList in testFunctions the behavior of the max function is the same because aList within the max function refers to whatever list max was given, not a specific list called aList .

It would probably help to rename one of your aList s to something different to avoid confusion.
