在 while 循環中計算用戶的平均值（通過提示輸入數據），直到 Python 中的某個條件

Question

我已經編寫了以下對我來說工作正常的代碼，我想在 function 中編寫相同的代碼（即 def function_name()）——我也在下面嘗試過，但這不是一個好方法，而且寫得不好） . 那么，如何修復代碼以及如何在調用/調用參數時將輸入輸入到我的 function 名稱的參數中，以便獲得最終答案。

# Normal code:
from statistics import mean 
lst = list()
while True:
    user_int = input("Enter a number: ")
    if user_int == "done":
        break
    try:
        float_user_int = float(user_int)
    except:
        print("Bad input. Enter a valid number")
        continue 
    lst.append(float_user_int)
print(mean(lst)) 

# Function Method I have tried which is working fine but it's poorly written and not yielding correct output. Rather, I am getting an error i.e., NameError: name 'float_user_input' is not defined. How can I write user_input integer numbers in an argument of my function name?

def avg_list(float_user_input):
    from statistics import mean # import statistics
    lst = list()
    while True:
        user_int = input("Enter a number: ")
        if user_int == "done":
            break
        try:
            float_user_int = float(user_int)
        except:
            print("Bad input. Enter a valid number")
            continue # quit()
        lst.append(float_user_int)
    return(mean(lst)) # statistics.mean()
print(avg_list(float_user_input))

# This is the one I tried and it seems to be working with function but I don't think this code is perfect because I have done nothing in it except copy pasting the entire code under def function statement. How can I put user input number in an argument of function name?

def avg_list():
    from statistics import mean # import statistics
    lst = list()
    while True:
        user_int = input("Enter a number: ")
        if user_int == "done":
            break
        try:
            float_user_int = float(user_int)
        except:
            print("Bad input. Enter a valid number")
            continue # quit()
        lst.append(float_user_int)
    return(mean(lst)) # statistics.mean()
print(avg_list())

您的幫助將不勝感激。 謝謝。

Answer 1

從 function 聲明和 function 調用中刪除float_user_input

Answer 2

我認為您想要一個 function ，它從用戶那里獲取輸入列表，例如get_input_list並計算如下平均值：

from statistics import mean # import statistics

def avg_list(input_list):
    return(mean(input_list))


def get_input_list():
    # Take user input here
    lst = list()
    while True:
        user_int = input("Enter a number: ")
        if user_int == "done":
            break
        try:
            float_user_int = float(user_int)
        except:
            print("Bad input. Enter a valid number")
            continue
        lst.append(float_user_int)
    return lst

# call function
print(avg_list(get_input_list()))
