这可能是一个愚蠢的问题,但我想知道其他人如何处理这个问题,或者是否有标准/推荐的解决方法。
以下是在python中将其打印到屏幕时拆分长文本行的两种方法。应该使用哪一个?
选项1
if some_condition: # Senseless indenting.
if another condition: # Senseless indenting.
print 'This is a very long line of text that goes beyond the 80\n\
character limit.'
选项2
if some_condition: # Senseless indenting.
if another condition: # Senseless indenting.
print 'This is a very long line of text that goes beyond the 80'
print 'character limit.'
我个人觉得选项1 丑陋,但选项2 似乎会违反通过第二次print
调用来保持简单的pythonic方式。

一种方法可以使用括号:
print ('This is a very long line of text that goes beyond the 80\n'
'character limit.')
当然,有几种方法可以做到这一点。另一种方式(如评论中所示)是三重引用:
print '''This is a very long line of text that goes beyond the 80
character limit.'''
就个人而言,我不喜欢那个,因为它似乎打破了缩进,但那只是我。

如果您有一个长字符串并且想要在适当的位置插入换行符,textwrap
模块提供了执行此操作的功能。例如:
import textwrap
def format_long_string(long_string):
wrapper = textwrap.TextWrapper()
wrapper.width = 80
return wrapper.fill(long_string)
long_string = ('This is a really long string that is raw and unformatted '
'that may need to be broken up into little bits')
print format_long_string(long_string)
这导致打印以下内容:
This is a really long string that is raw and unformatted that may need to be
broken up into little bits
