'练习读取StingIO和BytesIO'

__author__ = 'sergiojune'

from io import StringIO, BytesIO

# StingIO和BytesIO 和在内存中读取数据，不是在文件中读取数据

s = StringIO('hello\nhi\ngood!\nheadsome boy') # 创建

# 进行读取,与文件读取差不多

for x in s.readlines():

print(x)

# 也可以这样创建

s = StringIO()

s.write('hello')

s.write(' ')

s.write('world')

print(s.getvalue())

# 这时BytesIO的练习,bytesIO是写入字节码，而SrtingIO是写入str

b = BytesIO('中文'.encode('utf-8'))

# print(b.getvalue())

print(b.read())
