Python - 字串作為檔案

在讀取檔案時，它作為具有多個元素的字典進行讀取。因此，我們可以使用元素的索引來訪問檔案的每一行。在下面的示例中，我們有一個具有多行的檔案，這些行成為檔案的各個元素。

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

# Print each line
	for i in range(len(data)):
    print "Line No- ",i 
    print data[i]

當我們執行上述程式時，我們會得到以下輸出 -

Line No-  0
Vito Corleone is the aging don (head) of the Corleone Mafia Family. 

Line No-  1
His youngest son Michael has returned from WWII just in time to see the wedding of Connie Corleone (Michael's sister) to Carlo Rizzi. 

Line No-  2
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. 

Line No-  3
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.

Line No-  4
This does not please Sollozzo, who has the Don shot down by some of his hit men. 

Line No-  5
The Don barely survives, which leads his son Michael to begin a violent mob war against Sollozzo and tears the Corleone family apart.

檔案作為字串

但是，整個檔案內容可以作為一個字串讀取，方法是刪除換行符並使用如下所示的 read 函式。在結果中沒有多行。

with open("Path\GodFather.txt", 'r') as BigFile:
    data=BigFile.read().replace('\n', '')
	
# Verify the string type 
	print type(data)
	
# Print the file content
    print data

當我們執行上述程式時，我們會得到以下輸出 -
