Python编程语言一经推出就凭借其简单易用这一特点极大的吸引了开发人员的注意。那么它的到来究竟给我们的编程方式带来了哪些改变呢？我们今天就来从Python for in的应用方法来体验这种变化。
Python for in代码示例：
- #!/usr/bin/env python
- 'makeTextFile.py -- create text file'
- import os
- ls = os.linesep
- # get filename
- while True:
- if os.path.exists(fname):
- print"*** ERROR: '%s' already exists" % fname
- else:
- break
- # get file content (text) lines
- all = []
- print "\nEnter lines ('.' by itself to quit).\n"
- # loop until user terminates input
- while True:
- entry = raw_input('> ')
- if entry == '.':
- break
- else:
- all.append(entry)
- # write lines to file with proper line-ending
- fobj = open(fname, 'w')
- fobj.writelines(['%s%s' % (x, ls) for x in all])
- fobj.close()
- print 'DONE!'
希望这里介绍的Python for in的实际应用示例能给大家在学习中带来些帮助。
