使用a=b=c判断
# 在Python中可以使用a == b == c连等的判定条件 if not (c == len(raw_str) == len(set(raw_str) & set(allow_number_str))): print 'invalid input format,LOOK THE HINT!!!' continue
for-else的使用
s = ('pat','cheh','fa','yas')
print 'Q1----------'
for food in s:
print food
if food == 'yas':
break
else:
#这个不会执行
print 'else in Q1'
print 'Q2-----------'
for food in s:
if food == 'ccc':
break
else:
#这个会被执行
print 'else in Q2'
简单请求IP查询API（PY2.x）
import urllib
def request_ip_address(self, ip):
res = None
url = 'http://ip.taobao.com/service/getIpInfo.php?ip={ip}'.format(ip=ip)
req = urllib2.Request(url)
try:
response_str = urllib2.urlopen(req)
if response_str:
res = json.load(response_str)
print res
except Exception as e:
print str(e)
os.path模块
import os # 基本路径 self.base_path = os.path.dirname(__file__) # 书本目录 self.book_path = os.path.join(self.base_path, self.src_dir) # 如果某一目录不存在就创建 if not os.path.exists(self.dst_book_dir): os.makedirs(self.dst_book_dir)
复制文件
import shutil def _copy_media(self, parent_path, file_name): src_path = os.path.join(parent_path, file_name) dst_path = os.path.join(self.dst_book_dir, file_name) if not os.path.exists(dst_path): shutil.copyfile(src_path,dst_path)
使用with语句读写文件
def _add_to_dst_file(self, file_path): with open(file_path, 'r') as fp: content = fp.read() if content: self.dst_fp.write(os.linesep) self.dst_fp.write(content)
使用cx_freeze打包同目录下的tk_demo.py程序
import sys
from cx_Freeze import setup, Executable
base = None
if sys.platform == "win32":
base = "Win32GUI"
includeFiles = [
( r"D:\py\tcl\tcl8.5", "tcl"),
( r"D:\py\tcl\tk8.5", "tk")
]
setup(
name = "tk_demo",
version = "1.0",
description = "A demo for tkinter",
options = {"build_exe": {"include_files": includeFiles,}},
executables = [Executable("tk_demo.py",base = base)])
