在python中长度不建议超过80，处理办法如下：
办法1：使用圆括号()隐式转换
url = ('https://mp.weixin.qq.com/s?__biz=MzI4MzM2MDgyMQ==&tempkey='
'OTMwX1pNbk5ETmVxTkkwdXpGaWo1RC1GZThwaHlzeHRRb2dfcjRFZmpF'

'Ym5iNWZmLXVMeDFBeThfZFpKa3VxNHpIT21hNnBTc244THRCQm1leTVSen'
'dVRk5zSnNIWldFaHUxRzRJ'
'aFU3OGd%2Bfg%3D%3D&chksm=6b8aad835cfd249522b213148affa25'
'de442377adfb83afec75e3321fc6059ff26d2ddd11e04#rd')
办法2：在行末添加转义符

OTMwX1pNbk5ETmVxTkkwdXpGaWo1RC1GZThwaHlzeHRRb2dfcjRFZmpF\
c2cyVDhBME82dl82dHVWdks5UD\
c2SFZtWTN3M2VQQ1BFalRpblpfZUFrdHpEbzBpUDR5OXZRS3N0VzE2WXp4\
Ym5iNWZmLXVMeDFBeThfZFpKa3VxNHpIT21hNnBTc244THRCQm1leTVSen\
dVRk5zSnNIWldFaHUxRzRJ\
aFU3OGd%2Bfg%3D%3D&chksm=6b8aad835cfd249522b213148affa25\

注意
不建议用r"""..."""括住代码，因为会在末尾添加换行符，见下文示例
示例
a = r"""jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj
jjjjjjjjjjjjjjjjjj"""
b = "jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj\
jjjjjjjjjjjjjjjjjjjjj"
c = ("jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj"
"jjjjjjjjjjjjjjjjjjjjj")
print("a输出为%s \n" % a)
print("b输出为%s \n" % b)
print("c输出为%s \n" % c)
打印结果：
a输出为jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj
jjjjjjjjjjjjjjjjjj
b输出为jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj
c输出为jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj
