Question

我无法理解为什么我在第78行的Python 3程序中不断收到此语法错误。我试图用两个参数调用一个函数。

reportHits(playerList, num)

我已经检查了缩进，间距，冒号，并在线查看，但我所做的一切都没有修复它。

非常感谢任何帮助！

def quit():
    """This function Quits the Baseball Database"""
    print("You are now leaving the Baseball Database")
    print("Program is terminating gracefully...")

def help():
    """This function displays a List of program functions to the user"""
    print("QUIT - to exit the progam")
    print("HELP - to display a list of functions")

    print("TEAM - to sort baseball database by team name identifier")
    print("REPORT - to sort baseball database by number of HITS")

Answer 1

        num = input(float("How many of the top players do you want to view?")
        reportHits(playerList, num)

您在上一行中缺少一个近似括号。
