import calendar

import time

列表

list1 = [“sdf”,”sdff”,”sdfdd”]

print list1[1]+”\n”

元组 元组与列表类似，不同之处在于元组的元素不能修改

tup1 = (‘physics’, ‘chemistry’, 1997, 2000);

print tup1[0]+”\n”

字典Dictionary(map)

dict = {‘Name’: ‘Zara’, ‘Age’: 7, ‘Class’: ‘First’}

print “dict[‘Name’]: “, dict[‘Name’]

print “dict[‘Age’]: “, dict[‘Age’]

输出当前时间

tim = time.strftime(“%Y-%m-%d %H:%M:%S”, time.localtime())

print tim

print tim.split(” “)[0]

输出月份日历

cal = calendar.month(2017, 6)

print “以下输出2016年1月份的日历:”

print cal;

while循环

count = 0

while (count < 9):

print ‘The count is:’, count

count = count + 1

for循环 str可以为字符串，列表，字典等

str = “spark”

for i in str:

print i

字典遍历

dict = {‘Name’: ‘Zara’, ‘Age’: 7, ‘Class’: ‘First’}

for i in dict.items():

print i[0]

print i[1]

dict1 = {‘Name’: ‘Zara’, ‘Age’: 7, ‘Class’: ‘First’}

for i in dict1.keys():

print i

print dict1[i]
