Python函数和格式不起作用

Question

我目前在python中遇到函数问题。这是我尝试将其放入函数之前的代码：

for i in range(4):
    for y in Days:
      for x in "ABCDEF":
        data = input("What was the punctuality for bus " + x + " on " + str(y) + ", Week " + str(Week) + "? ")
        Bus = "Bus" + str(x)
        Buses[Bus].append(str(data))
        print()
    Week += 1

它的工作与预期的一样，但是我尝试将其放在函数中：

def InputData():
  for i in range(4):
    for y in Days:
      for x in "ABCDEF":
        data = input("What was the punctuality for bus " + x + " on " + str(y) + ", Week " + str(Week) + "? ")
        Bus = "Bus" + str(x)
        Buses[Bus].append(str(data))
        print()
    Week += 1

整个星期+ = 1部分我都出错了。他们说：

[pyflakes] local variable 'Week' (defined in enclosing scope on line 11) 
referenced before assignment
[pyflakes] local variable 'Week' is assigned to but never used

任何帮助将不胜感激。

Answer 1

Week = 0

将此代码放在代码的开头。
