'AttributeError：'模塊'對象沒有屬性'randomVariable''

Question

我有2個文件被導入到主文件，並且運行。

當我運行它，我不斷收到錯誤：

dice_sides = random_var.randomVariable() 
AttributeError: 'module' object has no attribute 'randomVariable' 
>>> 

我的代碼：主文件：

import random, random_var, dice_roll 

dice = [4, 6, 12] 

def main(): 
    dice_sides = random_var.randomVariable() 
    dice_roll.diceRoll(dice_sides) 

main() 

Random_var文件：

import random, task_one # import modules and file to be used in program 

dice = [4, 6, 12] # declare list 

def randomVariable(): # function 

    try: # tries this expression 
     dice_sides = int(input("Please enter the amount of sides you want the dice that is being thrown to have. The sides available are: 4, 6 and 12: ")) 
    except ValueError: # if user entered anything other than an integer 
     print("You did not enter an integer. Program restarting.") 
     task_one.main() # restarts, by getting the main function from "task_one" file 

    return dice_sides; # returns variable so it can be used in other functions 

Dice_roll文件：

import random, task_one 

dice = [4, 6, 12] 
def diceRoll(dice_sides): 

    if dice_sides in dice: 
     diceThrown = random.randrange(1, dice_sides) 
     print(dice_sides, " sided dice, score ", diceThrown) 
    else: 
     print("Number is invalid. Please choose either 4, 6 or 12. ") 
     task_one.main() 

有什麼問題？

Answer 1

最有可能的解釋是random_var不是你認爲的那樣。

如果您在交互式解釋器中運行此操作，請關閉並重新啓動它，以確保重新裝入模塊。

除此之外，請確保您保存random_var.py，其文件名是否正確（包括大小寫），並且它一直保存在那裏import random_var正在尋找它（即您還沒有結束了兩個random_var.py文件在不同的目錄中）。

Answer 2

你可以試試：

import random 
from random_var import randomVariable 
from dice_roll import diceRoll 

dice = [4, 6, 12] 

def main(): 
    dice_sides = randomVariable() 
    diceRoll(dice_sides) 

main()
