[Python知识库]Python-file的文件类型

源代码如下：

# .exe .txt .ppt .avi .jpg .mp4
f = open('D:\\SuShi.txt')   # 默认为 r
print(f.read())
print(f.tell())         # 文件长度
f.seek(9, 0)            # 指针定位（从7开始，到末尾）
print(f.readline())     # 整行输出
print('-----------')
f.seek(0, 0)
for each_line in f:
    print(each_line)
f.close()

print('-----------------------------')

# 编写文件
f = open('D:\\test.txt', 'w')
f.write('我爱静静')
f.close()

f = open('D:\\test.txt')
print(f.read())

运行结果如下：

A:I love JingJing.
B:Romeo, take me somewhere we can be alone.
----------------------------------------------
A:I'll be waiting; all there's left to do is run.
B:You'll be the prince and I'll be the princess
----------------------------------------------
A:It's a love story baby just say :"Yes"
