如何将变量写入python3.7文件

Question

我正在保存python的一个分数文件，但它出现了一个错误 当我试图保存一个由用户创建并在整个程序中更改的变量时

我试图改变它，但没用

def CreateFile():
   global CreateFile
   CreateFile = open("Score.txt", "w")
   CreateFile.write(p1,"Had",p1sc," points") 
   CreateFile.write(p2,"Had",p2sc," points")
   if p1sc > p2sc:
      CreateFile.write(p1," won with",p1sc," points")
      CreateFile.write(p2," lost with",p2sc," points")
   elif p2sc > p1sc:
      CreateFile.write(p2," won with",p2sc," points")
      CreateFile.write(p1," lost with",p1sc," points")

print("The score's have been saved in a file called 'Score.txt' ")
CreateFile()

p1和p2是输入变量 p1sc和p2sc是可以改变的变量

我收到的错误消息是：

  Exception has occurred: TypeError
write() takes exactly one argument (4 given)
  File "/Users/joshua/Desktop/aaHomeProjects/Programming/PythonProjects/DiceGame2ElecticBoogaloo.py", line 248, in CreateFile

Answer 1

您得到的特定错误是由于错误地使用了file.write()。与print()不同的是，file.write()需要一个字符串参数，而print()接受任意数量的位置参数并自动将它们与空格连接起来。你知道吗

在您的例子中，应该用write(f"{p1} Had {p1sc} points")（Python 3.6+）或write("{p1} Had {p1sc} points".format(p1=p1, p1sc=p1sc))（Python 3.5及更早版本）等格式字符串替换所有write(p1,"Had",p1sc," points")等调用。你知道吗

除此之外：

1. 请参阅关于全局名称的注释。一般来说，尽可能避免声明全局变量（例如，应将变量p1、p1sc、p2、p2sc作为参数传递），并注意函数和变量共享同一命名空间。如果给CreateFile赋值，将覆盖CreateFile()函数，并且不能再在同一作用域中调用CreateFile()。

2. 在Python中，打开文件时使用with块也是一种常见的做法，它会在完成后隐式关闭文件：

你知道吗

def CreateFile(p1, p1sc, p2, p2sc):
   with open("Score.txt", "w") as file:
       file.write(f"{p1} Had {p1sc} points")
       # etc
