我正在尝试从用户输入(python3.x)附加到文件，不明白为什么这段代码不起作用

Question

我的代码基本上将用户输入并将其放入文件中。当我运行它时，代码会创建文件，但始终为空。你能帮我吗？

  #Asks file name from user.
  FileName = input("Please provide a name for your file: (no spaces) ")
  FileFullName = FileName + ".txt"
  TypeInput = input("What would you like to type? ")
  FileLine = TypeInput + "n"
  #Opens file & puts user input into file.
  saveFile = open(FileFullName, 'a')
  saveFile.write(FileLine)
  print("All finished!")
  saveFile.close()

使用with open，因此您不需要关闭文件。它是这样的工作：

#Asks file name from user.
FileName = input("Please provide a name for your file: (no spaces) ")
FileFullName = FileName + ".txt"
TypeInput = input("What would you like to type? ")
FileLine = TypeInput + "n"
#Opens file & puts user input into file.
with open(FileFullName, 'a') as saveFile:
    saveFile.write(FileLine)
print("All finished!")
