有人可以看看我的代码来提供帮助和验证技术，使其在我的变量上只输入 0 到 120 之间

Question

def readFromFile():    
    clientID = input("Enter your clientID: ")
    clientFile = open("clientIntensity.txt","r")
    for record in clientFile:
        if record.startswith(clientID):
            print ("Your intensity is", record[6:14])
            intensity = record[6:10]
            if intensity == "High":
                print(" Running n Swimming n Aerobics n Football n Tennis")
            else:
                print(" Walking n Hiking n Cleaning n Skateboarding n Basketball")
    clientFile.close()
readFromFile()
def Time():
    Running = int(input("Please enter the ammount of minutes you spent Running: "))
    Swimming = int(input("Please enter the ammount of minutes you spent Swimming: "))
    Aerobics = int(input("Please enter the ammount of minutes you spent doing Aerobics: "))
    Football = int(input("Please enter the ammount of minutes you spent playing Football: "))
    Tennis = int(input("Please enter the ammount of minutes you spent playing Tennis: "))
Time()
print(clientID)
print("The ammount of time spent exercising this week is",Running+Swimming+Aerobics+Football+Tennis)

这是我拥有的代码，我不断收到语法错误：

Traceback (most recent call last):
  File "C:UsersUserDesktopControlled AssessmentRecorder.py", line 26, in <module>
    print(clientID)
NameError: name 'clientID' is not defined:

谁能帮忙？我需要它，以便它将打印用户先前在代码开头输入的clientID。也可以有人帮助使用验证技术来制作它，以便用户只能为活动变体输入 0 到 120 之间的数字，例如"正在运行"

Answer 1

clientId = ""
Running = -1
Swimming = -1
Aerobics = -1
Football = -1
Tennis = -1
def readFromFile():
    global clientID
    clientID = input("Enter your clientID: ")
    clientFile = open("clientIntensity.txt","r")
    for record in clientFile:
        if record.startswith(clientID):
            print ("Your intensity is", record[6:14])
            intensity = record[6:10]
            if intensity == "High":
                print(" Running n Swimming n Aerobics n Football n Tennis")
            else:
                print(" Walking n Hiking n Cleaning n Skateboarding n Basketball")
    clientFile.close()
readFromFile()
def my_input(event):
    num = -1
    while not 0 <= num <= 120:
        num = int(input("Please enter the ammount of minutes you spent " + event + ": "))
    return num
def Time():
    global Running, Swimming, Aerobics, Football, Tennis
    Running = my_input('Running')
    Swimming = my_input("Swimming")
    Aerobics = my_input("Aerobics")
    Football = my_input("Football")
    Tennis = my_input("Tennis")
Time()
print(clientID)
print("The ammount of time spent exercising this week is",Running+Swimming+Aerobics+Football+Tennis)

Answer 2

clientId是在函数readFromFile的本地命名空间中定义的。

然后，尝试在全局命名空间中使用 print 调用它，而全局命名空间不存在它。

最好将clientId返回到变量中，如下所示：

def readFromFile():    
    clientID = input("Enter your clientID: ")
    with open("clientIntensity.txt","r") as clientFile:
        for record in clientFile:
            if record.startswith(clientID):
                print ("Your intensity is", record[6:14])
                intensity = record[6:10]
                if intensity == "High":
                    print(" Running n Swimming n Aerobics n Football n Tennis")
                else:
                    print(" Walking n Hiking n Cleaning n Skateboarding n Basketball")
    return clientID
clientID = readFromFile()
... # your time function here
print(clientID)

这将按原样运行代码，但将clientID返回给变量，允许在全局命名空间中声明它（作为您将其返回的任何变量，在这种情况下仍然clientID）。然后可以将其传递给打印。

还值得注意的是，您读取文件的方式是非pythonic的，最好使用with子句，这比使用file.open()更安全（我在上面的代码中使用了with子句）

@MikeStainer。在代码开头添加以下内容：

clientId = ""
Running = -1
Swimming = -1
Aerobics = -1
Football = -1
Tennis = -1

在readFromFile函数的开头，添加global clientId在Time函数的开头，添加 global Running, Swimming, Aerobics, Football, Tennis 。这允许函数访问全局变量。

如果要强制使用 0 到 120 之间的值，只需使用 while 循环，重新分配变量，直到它们满足这样的约束。
