语法
以下是read()方法的语法:
fileObject.read( size );
参数
- size -- 这是可以从文件中读取的字节数。
返回值
此方法返回读取字符串中的字节数。
例子
下面的例子显示了read()方法的使用。
#!/usr/bin/python # Open a file fo = open("foo.txt", "rw+") print "Name of the file: ", fo.name # Assuming file has following 5 lines # This is 1st line # This is 2nd line # This is 3rd line # This is 4th line # This is 5th line line = fo.read(10) print "Read Line: %s" % (line) # Close opend file fo.close()
当我们运行上面的程序,它会产生以下结果:
Name of the file: foo.txt Read Line: This is 1s
