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。
代码语言：javascript代码运行次数：0运行复制a = 1
b = 2
c = a +\
b
print(c)>>> 3
代码语言：javascript代码运行次数：0运行复制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
代码语言：javascript代码运行次数：0运行复制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
2.三引号代码语言：javascript代码运行次数：0运行复制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：
代码语言：javascript代码运行次数：0运行复制print('''
_____ .__ .__ _____ __
/ _ \ ______ ____ |__||__| / _ \ _______ _/ |_
/ /_\ \ / ___/_/ ___\ | || | / /_\ \\_ __ \\ __\-
/ | \ \___ \ \ \___ | || | / | \| | \/ | |
\____|__ //____ > \___ >|__||__| \____|__ /|__| |__|
\/ \/ \/ \/
''')
