正则表达式转义字符串的一部分

Question

I am new to python and I need to remove 'Rs.' from 'Rs. 150.00'.But if I remove '.' it removes dot from numeric digits also. Following is my code:

price = re.sub('/[^0-9_.]\Rs.\/', '','Rs. 150.00')

Any help will be appreciated.

Answer 1

Can't you simply do string replacement:

>>>'Rs. 150.00'.replace('Rs.', '').strip()
'150.00'

Provided that you have more details in the string:

>>> re.search(r'\d+\.\d+', 'hello Rs. 150.00').group()
'150.00'

>>> re.search(r'\d+\.\d+', 'hello Rs. 150.00 and some more text').group()
'150.00'

This regular expression doesn't replace but finds a match for the digits.

Answer 2

Just like that it should work without grab the . between your number.

/Rs./
