Python 日期，時間和函數的使用

日期和時間的簡單使用

code

#導入time子產品
import time
#導入calendar(月曆)子產品
import calendar
#得到毫秒時間
ticks = time.time()
print ticks
#将毫秒時間轉換為本地時間
localTime = time.localtime(ticks)
print localTime
#格式化時間
localTime = time.asctime(localTime)
print localTime
#輸出指定月份的月曆
cal = calendar.month(,)
print cal
           

函數

#格式
def function_name(param):
  "文檔，函數介紹"
  sentence
  return [傳回值]
           

code

#一個簡單的輸出函數
def printMSG(msg):
    print msg
printMSG("TestInfo")
#有傳回值的簡單函數
def add(num1,num2):
    return num1 + num2
print add(,)
def printinfo(name,age):
    print "Name:",name,",Age:",age

printinfo("八戒",)
printinfo(age=,name="唐僧")
#報錯
#printinfo(age=600,"孫悟空")
#printinfo(name="孫悟空",600)
#有預設值的函數
def printinfo_02(name,age=):
    print "Name:",name,",Age:",age
printinfo_02("小白龍")
printinfo_02("沙和尚",)

#不定長參數的函數
