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]
