python文件操作（2）

#python文件读写对象
x,y,z = 1,2,3
name='woxiaoe'
d={'a':1,'b':2}
l = ['a','b','c']
file = open('object','w')
file.write(name + '\n')
file.write('%s,%s,%s\n' %(x,y,x));
file.write(str(d) + '$' + str(l) + '\n'); 
file.close();

#读入
file = open('object','r');
bytes = file.read();
print(bytes);
file.close();

file = open('object','r');
print(file.readline());
print(file.readline().split(','))
str = file.readline();
print(eval(str.split('$')[0]))
print(eval(str.split('$')[1]))
