I wanted to do the "no numerals" challenge where I need to change the numbers 0-10 with their names and the rest as digits.
Suppose the text is: "7 is an odd number while 4 and 6 are even 9, on the other hand is odd. 24 times 2 is 48"
The result should be: "seven is an odd number while four and six are even nine, on the other hand is odd. 24 times two is 48"

I want to do this in python

Answer 1

Why don't you split your text and check each word?

Answer 2

Are you worried for about something like
"41,"?

Answer 3

with comma

Answer 4

Oh yes

Answer 5

import re

a = "7 41, arnab23"
for w in a.split():
print(*re.findall(r'[0-9]+', w))

Answer 6

Did you try to run it once?
Anyway, [0-9]+ is a regex(a regex is used for find patterns in a string).

The pattern we want is sequence of digits from a string and for that we added this "[0-9]+" ( [0-9]+ matches one or more digits such as '123', '000')

for example, for a string "arnab266"
the regex would return 266 ignoring all the letters like isdigit() does.

Answer 7

Arnab Das In the challenge No numerals, if I'm not wrong there such inputs like "44," or number than 10. So this code much work fine.

However, if want to make a more dynamic one like where handles comma or any characters or for large number like 88 etc then I think you need to learn more and add extra thing like for example regex or some more basic string algorithms to built it.

Answer 8

I think I need to learn more... Thanks!

Answer 9

Sorry, I am very new to programming but
I tried that, but then if the digits have commas after them, then the element will have commas with the numbers.
Now, I tried to do that by removing the commas and then changing them and....... It creates a mess which is very hard for me to understand.
Python is my first language, so I don't know python completely. Thanks for replying.... Waiting for another

Can you please tell me why the try and except statement are not working? It still shows value error

Answer 11

Sorry I am a very beginner so I am not sure what this code means. Could you please explain it to me?

Answer 12

Yes I ran it. I actually don't know anything about the python modules, so I tried to code it with the inbuilt functions.
Isn't there no way to do it without using any modules?
