Question

我是Python的绝对初学者，我的任务是创建一个可以做一些事情的程序：

将员工姓名输入列表。
输入员工姓名后的工资。
在工作清单中记录工资，（2个清单：姓名[]和工资[]）。
查看总计后的平均工资。
打印那些平均薪水在5,000美元以内的员工（我被困的地方）。

请参阅下面的代码：

# function to total the salaries entered into the "newSalary" variable and "salaries[]".
def totalSalaries(salaries):
    total = 0
    for i in salaries:
        total += i
    return total

# Finds the average salary after adding and dividing salaries in "salaries[]".
def averageSalaries(salaries):
    l = len(salaries)
    t = totalSalaries(salaries)
    ave = t / l
    return ave

# Start main
def main():
    # Empty names list for "name" variable.
    names = []

    # Empty salaries list for "salary" and "newSalary" variables. 
    salaries = []

    # Starts the loop to input names and salaries.
    done = False
    while not done:
        name = input("Please enter the employee name or * to finish: ")
        salary = float(input("Please enter the salary in thousands for " + name + ": "))

        # Try/except to catch exceptions if a float isn't entered.
        # The float entered then gets converted to thousands if it is a float. 
        try:
            s = float(salary)

        # Message to user if a float isn't entered. 
        except:
            print("Please enter a valid float number.")
            done = False
        newSalary = salary * 1000

        # Break in the loop, use * to finish inputting Names and Salaries.
        if name == "*":
            done = True

        # Appends the names into name[] and salaries into salaries[] if * isn't entered.
        # Restarts loop afterwards if * is not entered. 
        else:
            names.append(name)
            salaries.append(newSalary)
    # STUCK HERE. Need to output Names + their salaries if it's $5,000 +- the total average salary.
    for i in range(len(salaries)):
        if newSalary is 5000 > ave < 5000:
            print(name + ", " + str(newSalary))

    # Quick prints just to check my numbers after finishing with *. 
    print(totalSalaries(salaries))
    print(averageSalaries(salaries))


main()

非常感谢任何信息。我希望这个程序中的其余功能和逻辑是有意义的。

你的避风港没有正确编写你的迭代器。使用数组，您只需使用var，循环将通过将每个元素放在元素中来迭代数组。因此，您的for循环变为for element in array:。

此外，您需要将您的条件分成两部分并使用添加和减法。你的代码应该检查工资是否高于或等于平均值减去5000，如果它低于或等于平均值加5000.如果你想用数学形式化它，那将是：工资＆gt; =平均值 - 5000 和薪水＆lt; =平均值+ 5000

因此，行的条件变为for salary in salaries

最后，在进入循环之前你不会调用averageSalaries，所以还没有计算平均工资。你应该调用函数并将结果放在for循环之前的变量中。

Python循环打印平均范围内的工资
