Python-从txt创建数组

Question

I'm trying to create an array of stock tickers in Python 2.7 from a txt file. The txt file simply has 1 ticker per line like:

SRCE
ABTX
AMBC
ATAX

The code I'm using looks like:

FinTick= []

    def parseRus():
        try:
        readFile=open(r'filename.txt','r').read()
        splitFile=readFile.split('\n')
        FinTick.append(splitFile)
        print FinTick



        except Exception, e:
        print str(e)

When I call 'parseRus()' I get an output that looks like:

'\xff\xfeS\x00R\x00C\x00E\x00\r\x00', '\x00A\x00B\x00T\x00X\x00\r\x00', '\x00A\x00M\x00B\x00C\x00\r\x00', '\x00A\x00T\x00A\x00X\x00\r\x00'

The correct letters are present but not printing in plane text. I've used a couple other logic methods to populate the array but still get the same output format.

Answer 1

>>> tickers = []
>>> with open("filename.txt", "r") as f:
        for ticker in f.readlines():
            tickers.append(ticker.strip())


>>> tickers
['SRCE', 'ABTX', 'AMBC', 'ATAX']

Try using readlines() and strip() instead.

Edit: Some clarity around f.readlines() and strip() :

>>> with open("filename.txt", "r") as f:
        print(f.readlines())

['SRCE\n', 'ABTX\n', 'AMBC\n', 'ATAX']

So, when we're iterating through the list object returned by f.readlines() , we will need to strip the newline \\n characters. Use the strip() method for str types to do this.

Edit 2: @Eli is right. We can just use for ticker in f instead of for ticker in f.readlines() , too.

>>> tickers = []
>>> with open("filename.txt", "r") as f:
        for ticker in f:
            tickers.append(ticker.strip())

>>> tickers
['SRCE', 'ABTX', 'AMBC', 'ATAX']

Answer 2

I finally figured a fix.

I had to modify the text file from 1 column to 1 row then saved as a .csv and modified the code to:

FinTick= []

def parseRus():
    try:
        readFile=open(r'filename.csv','r').read()
        splitFile=readFile.split(',')
        for eachLine in splitFile:
            splitLine=eachLine.split(',')
            ticker=splitLine[0]
            FinTick.append(ticker.strip())



    except Exception, e:
    print str(e)
