[Python] Python Classic Examples

Python Classic Example 1

Title: If a number is exactly equal to the sum of its factors, this number is called the "end number". For example, 6=1+2+3. Programming to find all the finished numbers within 1000.

#!/usr/bin/python#-*-Coding:utf-8-*- fromSysImportStdOut forJinchRange2,1001): K = [] n =-1s = j forIinchRange1, j):ifJ% i = =0: n + =1S-= i k.append (i)ifs = =0:PrintJ forIinchRange (N): Stdout.write (str (k[i))) Stdout.write ("')PrintK[n]

Monkey Eat Peach Problem: The first day the monkey picked up a number of peaches, ate half, not addicted, and ate a second morning and the rest of the peach eaten half, and eat one more. Every morning after eating the rest of the day half of the zero one. When I want to eat again in the morning of the 10th day, I see only one peach left. For the first day to pick a total number.

#!/usr/bin/python# -*- coding: UTF-8 -*-1forin range(9,0,-1):    12    x2 = x1print x1

range(self, begin, stop, step)

A simple math problem.

Title: a 5-digit number, judging whether it is a palindrome number. That is, 12321 is a palindrome number, single-digit and million-bit the same, 10 bits and thousands of the same.

#!/usr/bin/python# -*- coding: UTF-8 -*-a = int(raw_input("请输入一个数字:\n"Trueforin range(len(x)/2):    if1]:        False        breakif flag:    print"%d 是一个回文数!" % aelse:    print"%d 不是一个回文数!" % a

You can use a negative number to represent the backward forward count.

4

Title: Output The value of the list in reverse order.

a = [‘one‘‘two‘‘three‘]forin a[::-1]:    print (i)

a[::-1] #表示从-1开始遍历

5

Title: Separate the list by commas.

L = [1,2,3,4,5‘,‘forin L)print (s1)

join #表示以什么为间隔点，产生新的字符串。

6

Displays the font color.

#!/usr/bin/python# -*- coding: UTF-8 -*-class bcolors:    ‘\033[95m‘    ‘\033[94m‘    ‘\033[92m‘    ‘\033[93m‘    ‘\033[91m‘    ‘\033[0m‘    ‘\033[1m‘    ‘\033[4m‘print"警告的颜色字体?" + bcolors.ENDC

Title: Output an array in reverse order.

Program analysis: Swap with the first and last one.

if‘__main__‘:    a = [9,6,5,4,1]    N = len(a)     print a    forin2):        11],a[i]    print a
