在 Python 3.3 中写入文件

Question

Can anyone give me advice on writing in files. This is in python 3.3. This error message just keeps on popping up.

Traceback (most recent call last):Line 28, in file.write(name_1,"and",name_2,"have a",loveness_2,"percent chance of falling in love") TypeError: write() takes exactly 1 argument (6 given)

And my code is this:

  if vowels_1 > vowels_2:
      loveness = vowels_2/vowels_1
      loveness_2 = loveness * 100
      print("It is ",loveness_2,"% possible of you falling in love")
      print("*********************************************")
      file.write("*********************************************")
      file.write(name_1,"and",name_2,"have a",loveness_2,"percent chance of 
      falling in love")

Answer 1

file.write is not the same as print ; as the error says, it only takes a single argument. You need to compose your string before passing it to that call.

One way to do that is with string formatting:

line = "{} and {} have a {} percent chance of falling in love".format(name_1, name_2, loveness_2)
file.write(line)

Answer 2

A comma separates arguments, so the interpreter thinks you're giving a bunch of arguments here. If you want to do a string concatenation, use '+'.

print('a' + 'b')
>>> 'ab'

A more pythonic way would be to use .format()

print('{} some text {}'.format('foo', 'bar')
>>>'foo some text bar'
