1. 定义一个print_lol函数来控制列表的缩进和写入位置
import sys """this is a new fuction, which work for a list""" def print_lol(the_list,indent=False,level=0,where=sys.stdout): """ one arguement is the_list""" for each_item in the_list: if isinstance(each_item,list): print_lol(each_item,indent,level+1,where) else: if indent: for tab_stop in range(level): print(" ",end='',file=where) print(each_item,file=where)
2. 将更新的代码安装到本地库
C:UsersericDocumentsPython ester>c:UsersericAppDataLocalProgramsPythonPython35-32python.exe setup.py install running install running build running build_py copying nester.py -> buildlib running install_lib copying buildlib ester.py -> c:UsersericAppDataLocalProgramsPythonPython35-32Libsite-packages byte-compiling c:UsersericAppDataLocalProgramsPythonPython35-32Libsite-packages ester.py to nester.cpython-35.pyc running install_egg_info Removing c:UsersericAppDataLocalProgramsPythonPython35-32Libsite-packagesiamericnester-1.6.1-py3.5.egg-info Writing c:UsersericAppDataLocalProgramsPythonPython35-32Libsite-packagesiamericnester-1.6.1-py3.5.egg-info
3. 前段代码格式化文件内容并分割将内容存入man和other两个对象,后段代码以写模式打开2个新的文件并man和other对象存入其中。(存入的过程中调用print_lol进行格式再处理)
import nester import sys man = [] other = [] try: data = open('sketch.txt') for each_line in data: try: (role, line_spoken) = each_line.split(':',1) line_spoken=line_spoken.strip() if role== 'Man': man.append(line_spoken) elif role == 'Other Man': other.append(line_spoken) except ValueError: pass data.close() except IOError: print ('The datafiel is missing!') try: with open('man_data.txt','w') as man_file: nester.print_lol(man,where=man_file) with open('other_data.txt','w') as other_file: nester.print_lol(other,where=other_file) except IOError as err: print('file error:' +str(err))
