Question

这是我到目前为止所拥有的。它一直有效，直到我添加了功能。我需要在代码中有两个功能，我不知道如何正确地工作并尝试了几种不同的方法。代码需要将X量的随机数写入文本文件。

import random

random_numbers = open('ran_numbers.txt', 'w')

def main():

    getRandom()
    writeFunction()

def getRandom():
    qty_numbers = int(input('How many random numbers should be written to the file? '))

    for count in range (qty_numbers):
        number = random.randint(1,500)

def writeFunction():
    random_numbers.write(str(number)+ '\n')
    random_numbers.close()
    print('Your list of random numbers have been written to the file named')
    print('ran_numbers.txt')

main()

Answer 1

改变这个：

random_numbers = open('ran_numbers.txt', 'w')

def main():

    getRandom()
    writeFunction()

def getRandom():
    qty_numbers = int(input('How many random numbers should be written to the file? '))

    for count in range (qty_numbers):
        number = random.randint(1,500)

对此：

random_numbers = open('ran_numbers.txt', 'w')

def main():

    getRandom()


def getRandom():
    qty_numbers = int(input('How many random numbers should be written to the file? '))

    for count in range (qty_numbers):
        number = random.randint(1,500)
        writeFunction(number)

因为，number是getRandom（）函数的局部变量，所以要么直接写入该函数本身的文件，要么返回main函数中的数字并将其传递给writeFunction（）

def main():
    number= getRandom()
    writeFunction(number)

您所做的是您的选择，但在一个区块中定义数字不起作用。

Answer 2

在创建随机数

之后，永远不会调用writeFunction（）

只需改变：

for count in range (qty_numbers):
    number = random.randint(1,500)

到此：

for count in range (qty_numbers):
    number = random.randint(1,500)
    writeFunction(number)

并更改行：

def writeFunction():

为：

def writeFunction(number):

最后将main（）更改为：

def main():

    getRandom()
    random_numbers.close()

并删除

random_numbers.close()

来自writeFunction（）

的

我希望这会对你有所帮助。

Answer 3

我认为你只需要有一个生成的数字列表并将它们传递给file_writer。以下是我对您的代码所做的更改：

import random
def main():
    random_result = getRandom()
    writeFunction(random_result)
def getRandom():
    qty_numbers = int(input('How many random numbers should be written to the file? '))
    res = []
    for count in range (qty_numbers):
        res.append(random.randint(1,500))
    return res 
def writeFunction(random_numbers_list):
    random_numbers = open('ran_numbers.txt', 'w')
    for number in random_numbers_list:
        random_numbers.write(str(number)+ '\n')
    random_numbers.close()
    print('Your list of random numbers have been written to the file named')
    print('ran_numbers.txt')
main()

Answer 4

如果你必须有两个功能，那么这将是一个更好的解决方案。将随机数放在列表中，然后将其传递给writeFunction函数。

import random

random_numbers = open('ran_numbers.txt', 'w')

def main():

    writeFunction(getRandom())

def getRandom():
    qty_numbers = int(input('How many random numbers should be written to     the file? '))

    nums = []
    for count in range (qty_numbers):
        nums.append(random.randint(1,500))
    return nums

def writeFunction(a_list):
    random_nums = '\n'.join([str(x) for x in a_list])
    random_numbers.write(random_nums)
    random_numbers.close()
    print('Your list of random numbers have been written to the file named')
    print('ran_numbers.txt')

main()
