.format字符串拼接 # -*- coding:utf8 -*- #不一一对应会报错 tp1 = "i am {}, age {}, {}".format("charon",18,"pluto") print(tp1) tp2 = "i am {2}, age {0}, {1}".format("charon",18,"pluto") print(tp2) tp2 = "i
1.字符串连接 >>> a = 'My name is ' + 'Suen' >>> a 'My name is Suen' >>> a = 'My name is %s'%'Suen' >>> a 'My name is Suen' >>> a = 'My name is %s, Age:%d'%('Suen', 18) >>> a 'My name is Suen, Age:18'>>
# format() 方法 {}代替元素 默认是从左往右开始取值 test = 'i am {},age {},{}'.format('xiaoma',18,'happy') print(test) i am xiaoma,age 18,happy test1 = ','xiaoma','happy') print(test1) i am xiaoma,age 18,happy test2 = ','xiaoma','happy') print(test2) i am 18,age 18,18
概述 在Python3中,字符串格式化操作通过format()方法或者f’string’实现.而相比于老版的字符串格式化方式,format()方法拥有更多的功能,操作起来更加方便,可读性也更强.该函数将字符串当成一个模板,通过传入的参数进行格式化,并且使用大括号{}作为特殊字符代替%. 位置设定 默认位置 不指定格式化位置,按照默认顺序格式化 S = 'I {} {}, and I\'am learning'.format('like', 'Python') print(S) 示例结果: I l
