"""
# 一：读相关操作
# 1、readline：一次读一行
# with open(r'g.txt',mode='rt',encoding='utf-8') as f:
# # res1=f.readline()
# # res2=f.readline()
# # print(res2)
#
# while True:
# line=f.readline()
# if len(line) == 0:
# break
# print(line)
# 2、readlines：
# with open(r'g.txt',mode='rt',encoding='utf-8') as f:
# res=f.readlines()
# print(res)
# 强调：
# f.read()与f.readlines()都是将内容一次性读入内存，如果内容过大会导致内存溢出，若还想将内容全读入内存，
# 二：写相关操作
# f.writelines()：
# with open('h.txt',mode='wt',encoding='utf-8') as f:
# # f.write('1111\n222\n3333\n')
#
# # l=['11111\n','2222','3333',4444]
# l=['11111\n','2222','3333']
# # for line in l:
# # f.write(line)
# f.writelines(l)
# with open('h.txt', mode='wb') as f:
# # l = [
# # '1111aaa1\n'.encode('utf-8'),
# # '222bb2'.encode('utf-8'),
# # '33eee33'.encode('utf-8')
# # ]
#
# # 补充1：如果是纯英文字符，可以直接加前缀b得到bytes类型
# # l = [
# # b'1111aaa1\n',
# # b'222bb2',
# # b'33eee33'
# # ]
#
# # 补充2：'上'.encode('utf-8') 等同于bytes('上',encoding='utf-8')
# l = [
# bytes('上啊',encoding='utf-8'),
# bytes('冲呀',encoding='utf-8'),
# bytes('小垃圾们',encoding='utf-8'),
# ]
# f.writelines(l)
# 3、flush：
# with open('h.txt', mode='wt',encoding='utf-8') as f:
# f.write('哈')
# # f.flush()
# 4、了解
with open('h.txt', mode='wt', encoding='utf-8') as f:
print(f.readable())
print(f.writable())
print(f.encoding)
print(f.name)
print(f.closed)
