简单python脚本实例画图-python入门脚本的简单示例
编程之家收集整理的这篇文章主要介绍了python入门脚本的简单示例，编程之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
感兴趣的小伙伴，下面一起跟随编程之家 jb51.cc的小编来看看吧。
python代码如下：
#!/usr/bin/python
#Filename: 1.py
i=5
print i
i=i+1
print i
s='welcome to my home! I will intorduce my family to you!'
print s,i
length=6
width=5
area=width * length
print 'The Area is',area
print 'The perimeter is',2 * (length + width)
for a in range(2,9):
print a
else:
print 'The loop is over!'
#!/usr/bin/python
#Filename: 3.py
x=raw_input('Enter the value of x: ')
def printMax(x,y)
if a>b:
print x,'is the maximum'
else:
print y,'is the manimum'
printMax(x,y)
#!/usr/bin/python
# Filename: 2.py
while True:
b = raw_input('Enter a sentense or words(exit for exit): ')
if b == 'quit' or b == 'exit':
break
elif len(b) < 3:
print 'your input is too short.The length of your input must over3. Please type again!'
continue
print 'Ok! The length of your input is over 3,your input is',b
print 'Done!'
[/code]
[code]
database=[
["zhang3","0111"],["li4","0112"],["wang5","0113"]
]
username=raw_input("what's your user name?")
id=raw_input("what's your id?")
if [username,id] in database: print "access granted"
[/code]
[code]
def bj(x):
if x<0:
print "the number is too small"
elif x>100:
print "the number is too big"
else: print "the number is right!"
x=input("please input a number:")
bj(x)
#读取文件的脚本
import os
if os.getcwd()!='/root':
os.chdir('/root')
try:
with open('hi.txt','r') as f:
print(f.readline(),end='')
f.close()
except IOError as err: #此写法仅适用于python3
print('File Error:' + str(err))
#!/usr/bin/python
import os
path1=os.getcwd()
path2=os.path.abspath('/usr/local/5.txt')
print('使用os.getcwd()获取的内容为' + path1)
print('使用os.path.abspath()获取的内容为' + path2)
#统计文件夹大小的脚本
import os
from os.path import join,getsize
def getdirsize(dir):
size = 0
for root,dirs,files in os.walk(dir):
size += sum([getsize(join(root,name)) for name in files])
return size
if __name__ == '__main__':
filesize = getdirsize('/tmp')
print ('There are ' + str(filesize/1024/1024) + 'Mbytes in /tmp')
#文件写入的简单脚本
import zipfile
f = zipfile.ZipFile('archive.zip','w',zipfile.ZIP_DEFLATED)
f.write('1.py')
f.write('/root/install.log')
f.close()
#压缩文件夹的脚本
#!/usr/bin/python
import zipfile
import os
f = zipfile.ZipFile('archive.zip',zipfile.ZIP_DEFLATED)
startdir = "/root/mydir"
for dirpath,dirnames,filenames in os.walk(startdir):
for filename in filenames:
f.write(os.path.join(dirpath,filename))
f.close()
#调用shell命令的脚本
#!/usr/bin/python
# -*- coding: utf-8 -*-
import os
import commands
a=commands.getstatusoutput('pwd')
b=commands.getstatusoutput('pwdaa')
print('正确命令的返回状态是: ' + str(a[0]))
print('正确命令的返回结果是: ' + a[1])
print('错误命令的返回状态是: ' + str(b[0]))
print('错误命令的返回结果是: ' + b[1])
c=os.popen('pwd')
print c.read().rstrip()
