Python – 将字符串作为文件

读取文件后，它被视为一个具有多个元素的字典。因此，我们可以使用元素的索引访问文件的每一行。 在下面的示例中，我们有一个包含多行的文件，这些行将成为文件的单独元素。

with open ("Path\GodFather.txt", "r") as BigFile:
    data=BigFile.readlines()

#打印每一行
    for i in range(len(data)):
    print "第",i,"行" 
    print data[i]

当我们运行上述程序时，我们会得到以下输出 −

第 0 行
Vito Corleone is the aging don (head) of the Corleone Mafia Family. 

第 1 行
His youngest son Michael has returned from WWII just in time to see the wedding of Connie Corleone (Michael's sister) to Carlo Rizzi. 

第 2 行
All of Michael's family is involved with the Mafia, but Michael just wants to live a normal life. Drug dealer Virgil Sollozzo is looking for Mafia families to offer him protection in exchange for a profit of the drug money. 

第 3 行
He approaches Don Corleone about it, but, much against the advice of the Don's lawyer Tom Hagen, the Don is morally against the use of drugs, and turns down the offer.

第 4 行
This does not please Sollozzo, who has the Don shot down by some of his hit men. 

第 5 行
The Don barely survives, which leads his son Michael to begin a violent mob war against Sollozzo and tears the Corleone family apart.

将文件作为字符串

但是，通过删除换行符并使用 read 函数，可以将整个文件内容作为单个字符串读取，如下所示。结果中没有多个行。

with open("Path\GodFather.txt", 'r') as BigFile:
    data=BigFile.read().replace('\n', '')

#验证字符串类型 
    print type(data)

#打印文件内容
    print data
