Hello I am trying to scrape a website and its going fine, till the point I try to save the data into a csv via csv module writer. I traced back to the data and find out that 7 años is the string which isn't allowing the data to store properly.
I READ A LOT ON THIS TOPIC BEFORE POSTING... BUT COULDN'T GRASP THE CONCEPT.
Python is throwing some encoding error which got me to reading and I found that csv module isn't capable of unicode.
Is there any suggestion?
Try to use following solution
def sanitize_string(string):
return string.replace('\t', '')
Try to encode the string using encode function
your_variable = sanitize_string("your string")
your_variable.encode('utf8')
Hope this will help you.

My problem:
I'm using beautiful SOAP in Python, and i want to know how do i get the concrete attribute such as "data-hk".
My code at the moment:
The output of the code is km/L, but i want the data about HK. How do i specifically select the right attribute within the span?
Many thanks in advance.
I tried the above code, and I've stated the result and output of it above.
Try this:
HK = cars.find("span", class_="variableDataColumn")["data-hk"]

I have trouble reading this csv file downloaded from kaggle. I have tried using the utf-8 encoding and it was still not able to read the csv file
There might be some special characters in the file.
import pandas as pd
df = pd.read_csv(r"file_path", encoding="latin1")
with open('filename.csv') as file_info:
print(file_info)
The encoding will be at the end.
data=pd.read_csv('filename.csv', encoding="encoding from file_info")
Works every time.

Which of the following regular expressions can be used to get the domain name?
I try the next code but it doesn't work, there is something that i'm doing wrong?
In the picture the another options
txt = 'I refer to https://google.com and i never refer http://www.baidu.com'
print(txt.findall(?<=https:\/\/)([A-Za-z0-9.]*))
You selected the correct regexp, you just have to quote it to use it in Python. You also need to call re.findall(), it's not a string method.
import re
txt = 'I refer to https://google.com and i never refer http://www.baidu.com'
print(re.findall(r'(?<=https:\/\/)([A-Za-z0-9.]*)', txt))
Here's a regex that'll get your URLs
http(s?)://(?:[a-z0-9](?:[a-z0-9-]{0,61}[a-z0-9])?\.)+[a-z0-9][a-z0-9-]{0,61}[a-z0-9]
It'll work for https://stackoverflow.com, http://example.com, https://example.com etc...
If you don't want the http or https just use this:
(?:[a-z0-9](?:[a-z0-9-]{0,61}[a-z0-9])?\.)+[a-z0-9][a-z0-9-]{0,61}[a-z0-9]

so my python application opens a link that would be found in my config file. I would like to make it so it would like to allow it to go to the website without doubling the %. Heres what I would want config.get('CONFIG', 'Website') the web address has a bunch of %'s in the link but when I run it, the process ends
I'm assuming you are using the configparser module?
If so, you can use ConfigParser(interpolation=None) to disable string interpolation (which controls the behavior of % characters in the config file).
(Or on older versions of Python, you may need to use RawConfigParser instead.)

I am trying to code a RFID access system that utilizes an actuator to turn on and off. I followed a simple tutorial that can be found here.
I completed the tutorial fully and now have encountered problems:
I noticed when following the tutorial, the "python" we were coding was different from actual Python... for example, we don't do the curly brackets to end anything. Is there a way I can program and have access to my RFID module with the normal "Python" that I learned?
I am having issues finding the syntax's attached to SimpleMFRC522, because from what I read, it is a simplified way to interact with the RFID reader. So shouldn't there be certain syntax/functions attached to it?
When running a simple program that reads a tags ID and TEXT associated with the tag, I come across errors that usually wouldn't be an error on the normal python, for example...
Python Code
After running that code (labeled 'Python Code'), I come across...
Actual Error
I am extremely confused and need guidance or referral to anything I could possibly learn to help me finish this project. All or any help is appreciated and seriously considered.
Similar issue to this post.
You cannot concatenate a string and an integer so you must pull the id out of the object then typecast it to a string:
unsure what the 'id' name is within the object but let's assume it's 'id'
... (code above)
try:
print('Place your tag to be read.')
id_obj, text = reader.read()
print('Your ID is ' + str(id_obj.id))
print('Your text is ' + text)
... (code below)
