三十四 Python文件操作

1 写文件

my_list = ["1", "2", "3"]

my_file = open("myfile.txt", "w")

for item in my_list:
    my_file.write(item + "\n")                my_file.writelines(my_list)           // 写多个

my_file.close()

2  读文件

my_file = open("myfile.txt", "r")
print(my_file.read())                    // 一次性读取整个文件
my_file.close()

my_file = open("myfile.txt", "r")
print(my_file.readline())                // 读一行
print(my_file.readline())                // 再读下一行
my_file.close()

3  循环读取文件

my = open("myfile.txt")

for line in my:
    print(line + " aaa ")
