1.将打印出来到台词保存到文件中，需要如下步骤：
1）创建一个空列表，名为man
2)创建一个空列表，名为other
3）增加一行代码，删除spoken_line不必要到空白符
4）给出条件和代码，根据role的值将spoken_line添加到适当到列表中
5）在屏幕输出各个列表（man和other）
man=[]
other=[]
try:
data=open('sketch.txt')
for each_line in data:
try:
(role,spoken_line)=each_line.split(':',1)
spoken_line=spoken_line.strip()
if role =='Man':
man.append(spoken_line)
elif role =='Other Man':
other.append(spoken_line)
except ValueError:
pass
except IOError:
print('the data file is missing')
可以输出两个新建的列表看一下输出的数据：
print(man)
print(other)
2.修改上述代码，将数据保存到磁盘文件中
man=[]
other=[]
try:
data=open('sketch.txt')
for each_line in data:
try:
(role,spoken_line)=each_line.split(':',1)
spoken_line=spoken_line.strip()
if role =='Man':
man.append(spoken_line)
elif role =='Other Man':
other.append(spoken_line)
except ValueError:
pass
except IOError:
print('the data file is missing')
try：
"""在这里以写到形式打开两个数据文件"""
man_file=open('man_data.txt','w')
other_file=open('other_data.txt','w')
"""使用print()函数将指定到列表保存到打开到磁盘文件"""
print(man,file=man_file)
print(other,file=other_file)
man_file.close()
other_file.close()
except IOError:
print('File error')
3.代码优化：上述代码中如果第二个print()调用导致一个IOError,则文件没有被正常关闭，数据可能被破坏，可以用finally扩展try
man=[]
other=[]
try:
data=open('sketch.txt')
for each_line in data:
try:
(role,spoken_line)=each_line.split(':',1)
spoken_line=spoken_line.strip()
if role =='Man':
man.append(spoken_line)
elif role =='Other Man':
other.append(spoken_line)
except ValueError:
pass
except IOError:
print('the data file is missing')
try：
man_file=open('man_data.txt','w')
other_file=open('other_data.txt','w')
print(man,file=man_file)
print(other,file=other_file)
except IOError:
print('File error')
finally:
man_file.close()
other_file.close()
