how to remove a charater from a string (python)

Question

I have a text file that contain a bunch of websites.

text = '"wadouri:https:\/\/dev.pluginslab.com\/dicomviewer\/wp-content\/plugins\/pl-dicom-viewer-amazon-s3\/assets\/cases\/8255\/20191209113141\/sagittal-00000001.dcm","wadouri:https:\/\/dev.pluginslab.com\/dicomviewer\/wp-content\/plugins\/pl-dicom-viewer-amazon-s3\/assets\/cases\/8255\/20191209113141\/sagittal-00000002.dcm","wadouri:https:\/\/dev.pluginslab.com\/dicomviewer\/wp-content\/plugins\/pl-dicom-viewer-amazon-s3\/assets\/cases\/8255\/20191209113141\/sagittal-00000003.dcm", etc'

I was able to extract each website into a list

However there are '/' character in my list I cant seem to remove.

could some one tell me where I got it wrong

Thanks

import re
import bs4 as bs
import urllib.request
import os

myfile = open('C:/test/test.txt', 'r')

regex  = re.compile(r'(?<=https).*?(?=dcm)')

dcm =[]
for line in myfile:
    matches = regex.findall(line)
    for m in matches:
        dcm.append (str('https' + m + 'dcm'))

for d in dcm:
    d.replace('/','')
    print(d)

you arent printing the modified string. use: print(d.replace('/','')) or d = d.replace('/','') — gbruenjes

What does this have to do with jQuery? It's a JavaScript library, and has nothing to do with Python. — Barmar

Are you sure you want to remove forward slashes? More likely it's the backslashes you want to remove. I'm not sure why you're getting them, unless this is a JSON file. But if it's JSON, you should be using the json module to parse it, not do your own string processing. — Barmar

You need to capture the output of d.replace('/','') into a new variable like this:

for d in dcm:
    new_string = d.replace('/','')
    print(new_string)

replace returns the replaced string. Check the doc here

You can use

for d in dcm:
    new_string = d.replace('/','')
    print(new_string)

String are immutable in Python, therefore you have to create a new string.

Position based replacement:

d = d[:pos] + d[(pos+1):]

Character based replacement:

d = d.replace('/','')

then to see new string

print(d)
