如何將列表和用戶號碼都傳遞給一個函數，並讓它顯示列表中所有大於用戶號碼的號碼？

Question

我需要將列表和用戶號碼都傳遞給一個函數，並讓它顯示列表中所有大於用戶號碼的數字。這就像我已經得到並卡住了。感謝您的任何提示。

import random 

def randnum(): 
    random_num = [random.randrange(1,101,1) for _ in range (20)] 
    random_num.sort() 
    return random_num 

def usernum(): 
    try: 
     user_num = int(input("Please enter a number 1 through 100: ")) 
     if user_num > 100 or user_num < 1: 
      print("Please try again.") 
      usernum() 
    except ValueError: 
     user_num = print("Error. Please try to use integers while entering a number 1-100") 
     usernum() 
    return user_num 

def main():

我認爲你缺少了一些代碼，但你的功能可能是類似的東西：

def getHigherNumbers(userNumber, listNumbers): 
    return [x for x in listNumbers if x > userNumber] 

也有是在你的usernum()了一個錯誤：

當有錯誤你應該使用return usernum()而不僅僅是usernum()，因爲會有遞歸。

要回答在評論你的問題，這裏是你的代碼如何能期待：

import random 

def randnum(): 
    random_num = [random.randrange(1,101,1) for _ in range (20)] 
    random_num.sort() 
    return random_num 

def usernum(): 
    try: 
     user_num = int(input("Please enter a number 1 through 100: ")) 
     if user_num > 100 or user_num < 1: 
      print("Please try again.") 
      return usernum() 
    except ValueError: 
     print("Error. Please try to use integers while entering a number 1-100") 
     return usernum() 
    return user_num 

def getHigherNumbers(user_num, random_num): 
    return [x for x in random_num if x > user_num] 

def main(): 
    random_num = randnum() 
    print('random nums : %s' % random_num) 
    user_num = usernum() 
    print('user num : %s' % user_num) 
    greater_nums = getHigherNumbers(user_num, random_num) 
    print('greeter numbers : %s' % greater_nums) 

if __name__ == '__main__': 
    main() 


# random nums : [1, 4, 11, 14, 18, 24, 27, 29, 31, 37, 37, 41, 45, 59, 59, 66, 83, 87, 90, 99] 
# Please enter a number 1 through 100: 12 
# user num : 12 
# greeter numbers : [14, 18, 24, 27, 29, 31, 37, 37, 41, 45, 59, 59, 66, 83, 87, 90, 99]
