读取csv文件时循环内的python rstrip用法

Question

I have a CSV file where I am looping and matching with my database for getting results according to these matches.

I encountered a problem in the case where there is a space at the end of the text. So I did my research and found that I need to add the rstrip function to remove spaces at the end of the text.

Here is my code:

with open(path, encoding='utf-8') as f:
    data = csv.reader(f, delimiter='|')
    for row in data:
        line = row[0]
        cleanline = line.rstrip()
        lines.append(cleanline)
        query = line

The code is not working. I tried also strings like /s or strip , and replace functions as well but nothing is working. What can be the reason? What am I doing wrong?

CSV File with empty space at the end:

Sistem en az 23.8  inç boyutlarında olmalıdır. 
1 adet HDMI port olmalıdır.

You could try the following approach:

import csv

path = 'input.csv'
lines = []

with open(path, newline='', encoding='utf-8') as f:
    data = csv.reader(f, delimiter='|', skipinitialspace=True)

    for row in data:
        lines.append([c.strip() for c in row])

print(lines)        

This removes all leading and trailing spaces from each cell in a row using the strip() command. Depending on your data, it might be just enough to add the additional skipinitialspace=True parameter. This though would not remove trailing spaces before the next delimiter. newline='' should also be used in Python 3.x when used with a csv.reader() .

The file you have given just contains lines of text, as such you could read it as follows:

lines = []

with open('input.csv', encoding='utf-8') as f_input:
    for line in f_input:
        lines.append(line.strip())

print(lines)

This would give you lines containing:

['Sistem en az 23.8  inç boyutlarında olmalıdır.', '1 adet HDMI port olmalıdır.']
