PYTHON教程之import模块

PYTHON教程之import模块

#1.引用其他文件的方法import time 指 import time 模块，这个模块可以python自带，
# 也可以是自己安装的，比如以后会用到numpy这些模块,需要自己安装。
import time
print(time.localtime())  #这样就可以print 当地时间了
#2.import time as __,__下划线缩写部分可以自己定义，在代码中把time 定义成 t.
import time as t
print(t.localtime()) # 需要加t.前缀来引出功能
#3.from time import time,localtime ,只import自己想要的功能.
from time import time, localtime
print(localtime())
print(time())
#4.from time import * 输入模块的所有功能
from time import *
print(localtime())
