Python文件写操作

Python向文件中写入内容可使用wirte()或者writelines()方法：

(1) write(str)

一次写入一行，参数为字符串str。

data = ['abc\n','def\n','123\n','xyz\n','&*\n']
with open('output.txt', 'w') as fp:
for eachstr in data:
fp.write(eachstr)

(2) writelines(seq)

一次写入多行，参数为字符串序列seq

data = ['abc\n','def\n','123\n','xyz\n','&*\n']
with open('output.txt', 'w') as fp:
fp.writelines(data)
