?read()方法讀取文件size個(gè)字節(jié)大小。如果讀取命中獲得EOF大小字節(jié)之前，那么它只能讀取可用的字節(jié)。
語(yǔ)法

以下是read()方法的語(yǔ)法：

            
fileObject.read( size );


          

參數(shù)

• ??? size -- 這是可以從文件中讀取的字節(jié)數(shù)。

返回值

此方法返回讀取字符串中的字節(jié)數(shù)。
例子

下面的例子顯示了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()


          

當(dāng)我們運(yùn)行上面的程序，它會(huì)產(chǎn)生以下結(jié)果：

            
Name of the file: foo.txt
Read Line: This is 1s
