Question

我对Python很新，需要帮助。我已经在网上搜索了几天，这有助于修复以前的错误，但我仍然坚持这一点。我知道这已被问过几次，我已经阅读了论坛;但是，我仍然无法解决这个问题。

我正在使用Python 3.4.4

此作业的目标是创建一个包含范围为1-100的50个数字的随机列表并打印出来。然后你必须采取相同的列表并删除重复的数字，并打印该列表。最终，应该打印2个列表，一个列表重复，一个列表没有。这是我的代码：

from random import randrange

def createList():
    print("A program that will generate a list of 50 random numbers then remove any duplicates.")
    for i in range(50):
        randList = randrange(101)
        print(randList)

def removeDuplicates(randList):
    uniqueList = []
    for i in randList:
        if i not in uniqueList:
            uniqueList.append(i)
    print(uniqueList)

def main():
    createList()
    removeDuplicates()

if __name__ == "__main__": main()

这是我的错误：

Traceback (most recent call last):
  File "C:/Python34/Python Assignments/test-randNumbs.py", line 20, in <module>
    if __name__ == "__main__": main()
  File "C:/Python34/Python Assignments/test-randNumbs.py", line 18, in main
    removeDuplicates()
TypeError: removeDuplicates() missing 1 required positional argument: 'randList'

首先，您需要将列表传递给removeDuplicates()函数。但是，要做到这一点，您还需要在createList()。

中返回随机创建的列表

from random import randrange

def create_list():
    rand_list = []
    print("A program that will generate a list of 50 random numbers then remove any duplicates.")
    for i in range(50):
        rand_list.append(randrange(101))
    print(rand_list)
    return rand_list

def remove_duplicates(rand_list):
    unique_list = []
    for i in rand_list:
        if i not in unique_list:
            unique_list.append(i)
    print(unique_list)

def main():
    rand_list = create_list()
    print('unique list:')
    remove_duplicates(rand_list)

if __name__ == "__main__": main()

TypeError：removeDuplicates（）缺少1个必需的位置参数：＆＃39; randList＆＃39;
