Question

我正在将名称和分数添加到文件中，并试图找出在将数据写入文件后如何启动换行符。到目前为止，这是我的代码，但是当我继续执行该文件时，所有变量都在同一行：

print "That's the game folks! You finished with a final score of...", points, 'points! Good game, you made the high score list! What is your name?'
name = raw_input()
w = open('Highscores', 'a')
w.write(name)
w.write(str(points))
w.close()

Answer 1

对unix使用\n或Windows使用\r\n。只需添加到字符串的末尾。

w.write(str(points) + '\n')

或

print "That's the game folks! You finished with a final score of...", points, 'points! Good game, you made the high score list! What is your name?\n'

Answer 2

执行以下操作，

print(name, points, sep=":", file="Highscores") # Mike:23

你甚至不必做str(points)。适用于任何数据类型。并默认添加换行符。与使用.write()的自定义杂技相比，它非常高效。（ Beazly ）

Answer 3

这在Py3中变得更漂亮了：

print("That's the game folks! You scored %i points! Your name?" % points)
with open('Highscores', 'a') as w:
    print('%s %i' % (input(), points), file=w)

如果您只想为每个用户输入一个条目（即特定用户的最高分数且没有重复项），您可以使用字典并执行以下操作：

>>> from ast import literal_eval
>>> def save_score(name, score):
...     try:
...         d = literal_eval(open('score').read())
...     except:
...         d = {}
...     if name not in d or d[name] < score:
...         d[name] = score
...         open('score', 'w').write(str(d))
...
>>> save_score('Jack', 5)
>>> save_score('Jill', 10)
>>> open('score').read()
"{'Jill': 10, 'Jack': 5}"

如何在Python中为字符串添加换行符？
