Python学习第一天

从网上找了个在线的文档 http://www.runoob.com/python/python-tutorial.html

就按照上面的例子学起来了，不过我开始学的是python3.5.1，不知道是否是太新了。

如下是第一天本身练习的简单内容，固然是按照文档写的例子，不过有的格式会有些不同

#!/usr/bin/python

# -*- coding:UTF-8 -*-

# filename:test.py

#

#part one

if True:

print ("Answer")

print ("True")

else:

print ("Answer")

print ("False")

#part 2

print ("hello python"); #the first note

#PART 3

input("\n\nPress the enter key to exit.")

#part 4

import sys; x='foo';sys.stdout.write(x + '\n')

#part 5

counter = 100 #zheng xing

miles = 1000.0 # fudianxing

name = "John" #zifuchuan

print (counter)

print (miles)

print (name)

str = "what\'s hello world"

print (str) 

print (str[0]) #OUTPUT the first character

print (str[2:5]) #output from the third to the fifth

print (str[2:]) # output from the third character

print (str*2) #output the str twice

print (str + 'test') # output the connected str

list=['abcd',786,2.33,'jade',19.3]

tinylist=[124,'jade']

print (list) # output list

print (list[0]) # output the first element

print (list[1:3]) #output from the second to the third

print (list[2:]) #output from the third to the last one

print (tinylist*2) # output twice

print (tinylist+list) #

tuple=('abdc',100,1.1,'jade',13.1)

list=['abcd',100,1.1,'jade',13.1]

#tuple[2]=1000 #this is a wrong grammar

list[2]=1000

 

print (tuple)

print (list)

dict = {}

dict['one'] = "this is one"

dict[2] = "this is two"

tinydict = {'name':'john','code':6734,'dept':'sales'}

print (dict['one'])

print (dict[2])

print (tinydict)

print (tinydict.keys())

print (tinydict.values())
