Some tips for Python

#coding: Utf-8

#数据交换
x = 6
y = 5
X, y = y, X
Print X
Print Y

#相当于:?
print "Hello" if False else "world"

#一种方式绑定不同类型的数据
NFC = ["Packers", "49ers"]
AFC = ["Ravens", "patriots"]
Print NFC + AFC
Print str (1) + "World"
print ' 1 ' + "world"
Print nfc,1

#注意浮点除法
Print 5.0/2
Print 2**5
Print. 3/.1
Print. 3//.1

#数值比较 very good
x = 2
If 3>x>1:
Print X
If 1<x>0:
Print X
#同时迭代两个列表
one = [' Packers ', ' Atteck ']
both = [' reaf ', ' Dedad ']
For a, b in Zip (one,two):
Print A + "vs." +b
#带索引的列表迭代
Teams = [' one ', ' one ', ' three ', ' four ']
For Index,team in Enumerate (teams): #enumerate枚举列举
Print Index,team

#过滤出偶数
numbers = [1,2,3,4,5,6,7]
even = []
For number in numbers:
If number%2 = = 0:
Even.append (number)
Print even
Even2 = [number for number in numbers if number%2==0]
Print Even2

#字典
Teams = [' Onee ', ' both ', ' three ', ' four ', ' five ', ' six ']
Print {Key:value for key,value in enumerate (teams)} #注意是根据for后面的顺序展示
#初始化列表
Items = [0]*3
Print items

#列表转换为字符串
Teams = [' one ', ' one ', ' one ', ' three ', ' four ', ' five ', ' six ']
Print teams
Print ",". Join (teams)

#从字典中获取元素
data = {' admin ': 1, ' name ': ' Max ', ' Three ': 4}
A = Data.get (' admin ', False)
Print a
Try
Is_admin = data[' name ']
Except Keyerror:
Is_admin = False
Print Is_admin

#获取列表的子集
x = [1,2,3,4,5,6,7]
Print X[:3]
Print X[1:3]
Print X[-5:]
Print X[1::2]

#3的倍数打印fizz 5 multiples print buzz both multiples print Fizzbuzz
For x in range (101):p rint "Fizz" [x%3*4::] + "Buzz" [x%5*4::] or X

#迭代工具 Random Combination
From Itertools import combinations
Teams = [' one ', ' one ', ' three ', ' four ']
For game in Combinations (teams,2):
Print game
