精心总结python所有的内置函数，戳进来补习一下！

取绝对值
a = abs(-95) print(a) 值有一个为假，就全为假 a = all([True,True,False]) print(a) 有一个为真，就全为真 a = any([False,True,True]) print(a) 返回一个可打印的对象字符串方式表示 a = ascii('0x\10000') b = ascii('b\x19') print(a,b) 将整数转换成二进制字符串 a= bin(95) print(a) 将以个数据转换成8进制 a = oct(95) print(a) 将一个数据转成十进制 a = int(95) print(a)
 将整数转换成十六进制字符串 a = hex(95) print(type(a)) 转为布尔类型 a = bool("") print(a) 转换成字节形式bytes a = bytes("吴永聪",encoding='utf-8') print(a) chr返回一个字符串，其ascii码是一个整形，比如chr(97)返回字符串穿"a",桉树i的范围在0-255之间。 a = chr(88) print(a) ord参数是一个ascii字符，返回值是一个对应的十进制整数 a = ord("X") print(a) 创建数据字典 ret = dict({"wyc":2,"two":3}) dict(zip(("one","two"),(2,3))) dict(one=2,two=1) print(ret) dir列出某个类型的所有可用方法 a = dir(list) print(a) help查看帮助文档 ret = help(list) print(ret) 分别取商和余数 a = divmod(9,5) print(a) #计算表达式的值 a = eval('1+2*5') print(a) exec用来执行存储在字符串或文件中的python语句 ret = exec(print("Hi,girl.")) print(ret) filter 过滤 li = [1,2,3,4,5,6,7] a = filter(lambda x:x>3,li) print(a) float浮点型 a = float(1) print(a) 判断对象是不是属于int实列,返回True和False a = 5 b = isinstance(a,int) print(b) globals 返回全局变量 locals 返回当前局部变量 name = "wyc" def h1(): a = 1 print(locals()) h1() print(globals()) map遍历序列，对序列中每个元素进行操作，最终获取新的序列 li = [11,22,33] def func1(arg): return arg + 1 new_list = map(func1,li) for i in new_list:print(i) max 返回集合中的最大值 max min 返回集合中的最小值 min a = [1,2,3,4,5,6,7] s = max(a) n = min(a) print(s,n) pow 返回x的y次幂 a = pow(2,10) print(a) t = pow(2,10,100) print(t) round 四舍五入 a = round(9.5) print(a) sorted 队集合排序 char = ["吴","123","1","25","a","b","c"] new_chat = sorted(char) print(new_chat) for i in new_chat: print(bytes(i,encoding='utf-8')) sum求和的内容 a = sum([1,2,3,4,5]) print(a) a = sum(range(6)) print(a) __import__通过字符串的形式，导入模块 comm = input("Please:") ccas = __import__(comm) ccas.f1() #需要做拼接时后加 fromlist=True m = __import__("lib."+comm,fromlist=True) print(m)
