1.数字类型 int -int(将字符串转换为数字) a = " print(type(a),a) b = int(a) print(type(b),b) num = " v = int(num,base=16) print(v) PS:type打印数据类型,base=16是把num以16进制格式打印出十进制结果. -bit_lenght(当前数字的二进制位数) age = 5 r = age.bit_length() print(r) PS:5的二进制数为101(三位数),所以打印结…
数字(int): 1.int()(将字符串换为数字) a = " print(type(a), a) b = int(a) print(type(b), b) num = "a" # 使用 int 方法时默认转换为十进制数 # 通过base来指定转换后的类型 v = int(num, base=16) print(v) 输出: <class 'str'> 123 <class 'int'> 123 10 2.bit_length() (当前数字的二进制…
Python常用功能函数汇总 1.按行写字符串到文件中 import sys, os, time, json def saveContext(filename,*name): format = '^' context = name[0] for i in name[1:]: context = context + format + str(i) context = str(context).replace('(','(').replace(')',')').replace(',',',').re…
基本数据类型 一.整型 如: 18.73.84 整型具备如下功能: class int(object): """ int(x=0) -> int or long int(x, base=10) -> int or long Convert a number or string to an integer, or return 0 if no arguments are given. If x is floating point, the conversion tr…
