Python学习_数据处理split方法

用open方法导入文件“sketch.txt”后，用split()方法进行分割：

>>> import os
>>> os.chdir('C:/Python33/HeadFirstPython/chapter3')
>>> data=open('sketch.txt')
>>> for each_line in data:
    (role,spoken)=each_line.split(':',1)  #使用split方法分割行数据
    print(role,end='')
    print('said: ',end='')
    print(spoken,end='') 

用with语句处理文件：

try:
    with open('its.txt',"w") as data:
        print ("It's...",file=data)
except IOError as err:
    print ('File error:'+ str(err))
