第三章《文件与异常》
1.文件的打开:
路径查看
import os
os.getcwd()
进入目录:
os.chdir(路径)
打开:
data=open('sketch.txt')
2.读取文件:
for each_line in data:
if not each_line.find(':')==-1:
(role,line_spoken) = each_line.split(':',1)
print(role,end='')
print(' said: ',end='')
print(line_spoken,end='')
注:该文件用:分割,其中split是用于分割部分,后面的1标识几位
2.异常:
try:
except
try:
data = open('sketch.txt')
for each_line in data:
try:
if not each_line.find(':')==-1:
(role,line_spoken) = each_line.split(':',1)
print(role,end='')
print(' said: ',end='')
print(line_spoken,end='')
except:
pass
except:
print('The data file is missing')
