I was wondering if in python it would be possible to extract certain integers from a variable and save it as a seperate variable for later use.
for example:
str1 = "numberone=1,numbertwo=2,numberthree=3"
newnum1 = [find first integer from str1]
newnum2 = [find second integer from str1]
answer = newnum1 * newnum2
print(answer)
Try findall:
num1, num2, num3 = re.findall(r'\d+', 'numberone=1,'
'numbertwo=2,'
'numberthree=3')
Now num1 contains the string 1, num2 contains 2, num3 contains 3.
If you want only two numbers (thanks to @dawg), you can simply use the slice operator:
num1, num2=re.findall(r'\d+', the_str)[0:2]
num1, num2=re.findall(r'\d+', the_str)[0:2]You have some choice for this :
using str.split() :
>>> [int(i.split('=')[1]) for i in str1.split(',')]
[1, 2, 3]
using regular expressions :
>>> map(int,re.findall(r'\d',str1))
[1, 2, 3]
(?<==)\d+(?=,|$)
Try this.See demo.

import re
p = re.compile(ur'(?<==)\d+(?=,|$)', re.MULTILINE | re.IGNORECASE)
test_str = u"numberone=1,numbertwo=2,numberthree=3"
re.findall(p, test_str)
