逐行读取文件并传递给方法

Question

我有一个文本文件，大约有10个句子。你知道吗

My Name is Kerry.
I am a female.
My pet is a cat.
It's name is Ronald.
I hate rats.

我想做的是从这个文本文件中读取一个句子，并将它传递给我编写的fineSearch方法。你知道吗

def fineSearch(wd):
    for line in wd:
        for word in line.strip().split():
            if word.endswith(('ts.','ld')):
                print word

主要

ws = linebylineread('tx.txt')
fineSearch("It's name is Ronald.") # THIS IS FOR DEMO PURPOSE ONLY.

NOTE: I WANT TO READ JUST ONE LINE AT A TIME FROM THE TX.TXT FILE AND PASS IT TO THE METHOD THAT I HAVE WRITTEN.

NOTE: I HAVE NOTICED THAT THE CODE WORKS WHEN I PASS THE WHOLE CHUNK OF TEXT AND NOT A LINE.

当我传递fineSearch(ws)时，它工作，但它读取整个文件，当我打印文本时，它显示为；My Name is Kerry.\n I am a female.\n My pet is a cat\n等。我只想能够发送一行到我编写的方法。你知道吗

如果需要代码在一行上工作，则需要按如下所示更改fineSearch(...)函数：

def fineSearch(wd):
    for word in wd.strip().split():
            if word.endswith(('ts.','ld.')): # test for ld. at end
                print word

然后，您可以使用以下代码逐行遍历文件。你知道吗

>>> with open('testFile.txt', 'r') as f:
        for line in f:
            fineSearch(line)


rats. # Output. If you wanted Ronald. too, you need to change `ld` in the code to `ld.`

您的初始代码似乎工作在一个行列表上，类似于readlines(...)提供的，但是readlines(...)将整个文件读入内存，而您似乎希望逐行遍历文件。你知道吗
