【python】代码换行的几种方法
代码太长怎么办，反斜杠\引号""" ‘’\'来帮忙！
在写list或者较长的字符串时候，或者多个循环造成IDE不够用时，就需要代码换行了。主要的代码换行有通用的反斜杠\和针对字符串起作用的三引号结构。
1.反斜杠
对于一般表达式来说，反斜杠后直接回车即可实现续行，使用的关键在于反斜杠后不能用空格或者其他符号。
python">a = 1b = 2
c = a +\
b
print(c)
>>> 3
longlist = [\'3D\',\'3-D\',\'3d\',\'3-d\',\'three-dimensions\',\'Three-Dimensions\',\'Three Dimensions\',\'THREE DIMENSIONS\',\'geometry\',\ \'Geometry\',\'GEOMETRY\',\'Geometric\',\'surface\',\'Surfaces\',\'Surface\',\'SURFACE\',\
\'3D Pose Estimation\',\'Pose\',\'POSE\',\'POINTCLOUD\']
print(longlist)
>>> [\'3D\', \'3-D\', \'3d\', \'3-d\', \'three-dimensions\', \'Three-Dimensions\', \'Three Dimensions\', \'THREE DIMENSIONS\', \'geometry\', \'Geometry\', \'GEOMETRY\', \'Geometric\', \'surface\', \'Surfaces\', \'Surface\', \'SURFACE\', \'3D Pose Estimation\', \'Pose\', \'POSE\', \'POINTCLOUD\']
对于字符串也有同样的效果
longstring = \'this is a long long long long long long long \string\'
print(longstring)
>>> this is a long long long long long long long string
2.三引号
longstring1 = \'\'\'this is a long long long long long long long string\'\'\'
print(longstring1)
longstring2 = """this is another long long long long long long long
string"""
print(longstring2)
this is a long long long long long long long string this is another long long long long long long long string
还可以实现ascii字符输出呢：
print(\'\'\' _____ .__ .__ _____ __
/ _ \ ______ ____ |__||__| / _ \ _______ _/ |_
/ /_\ \ / ___/_/ ___\ | || | / /_\ \\_ __ \\ __\-
/ | \ \___ \ \ \___ | || | / | \| | \/ | |
\____|__ //____ > \___ >|__||__| \____|__ /|__| |__|
\/ \/ \/ \/
\'\'\')
#注意art中的反斜杠被动换行
>>> _____ .__ .__ _____ __
/ _ \ ______ ____ |__||__| / _ \ _______ _/ |_
/ /_\ \ / ___/_/ ___\ | || | / /_\ \_ __ \ __\-
/ | \ \___ \ \ \___ | || | / | \| | \/ | |
\____|__ //____ > \___ >|__||__| \____|__ /|__| |__|
\/ \/ \/ \/
