# Python learning
# coding:utf-8

# 1.读相关操作
# f.readline()  读一行
# with open(r"a.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)

# f.readlines()  读多行组成一个列表
#     res = f.readlines()
#     print(res)

# 2.写相关操作
# f.writelines()    从列表中循环写入，写入内容只能是str
l1 = [‘111‘, ‘222‘, ‘333‘]
# with open(r"c.txt", mode="wt", encoding="utf-8") as f:
#     res = f.writelines(l1)

l2 = [b‘111aaa‘, b‘222bbb‘, b‘333ccc‘]      # 纯英文字符
with open(r"c.txt", mode="wb") as f:
    res = f.writelines(l2)

l3 = [‘哈哈哈aaa‘.encode("utf-8"), ‘哈哈哈bbb‘.encode("utf-8"), ‘哈哈哈ccc‘.encode("utf-8")]      # 中文字符字符
with open(r"c.txt", mode="wb") as f:
    res = f.writelines(l3)

# 3.f.flush   刷新    将写入的内容刷新到硬盘
with open("c.txt", mode="wt", encoding="utf-8") as f:
    f.write("哈哈哈")
    f.flush()
