整型int 整数类型有4种进制表示:十进制、二进制(0b)、八进制(0o)和十六进制(0x)。 浮点型float Python语言中要求浮点数类型必须带有小数部分,小数部分可以是0,浮点型不支持二进制、八进制和十六进制 复数 可通过complex(re,im)或者a + bj创建 .复数类型中实部和虚部都是浮点类型,对于复数z,可以用z.real和z...
一、集合的使用 集合是一个无序的,不重复的数据组合,它的主要作用如下: 去重,把一个列表变成集合,就自动去重了 关系测试,测试两组数据之前的交集、差集、并集等关系 代码语言:javascript 复制 list_1= [1,4,5,7,3,6,7,9]list_1=set(list_1)print(list_1,type(list_1))list_2=set( ...

The string functionlen()returns the number of characters in a string. This method is useful for when you need to enforce minimum or maximum password lengths, for example, or to truncate larger strings to be within certain limits for use as abbreviations. ...
The sub-merchant can't access the 6-character string—we automatically append it to the descriptor name after you submit the transaction request. The string can't be changed, as it is required in order to identify each transaction we process for the sub-merchant. ...
