How to remove some dots from a string in python

Question

I'm extracting an int from a table but amazingly comes as a string with multiple full stops. This is what I get:

p = '23.4565.90'

I would like to remove the last dots but retain the first one when converting to an in. If i do

print (p.replace('.',''))

all dot are removed How can I do this.

N/B Tried a long way of doing this

p = '88.909.90000.0'
pp = p.replace('.','')
ppp = list(''.join(pp))
ppp.insert(2, '.')
print (''.join(ppp))

BUT discovered that some figures come as e.g. 170.53609.45 and with this example, I'll end up with 17.05360945 instead of 170.5360945

Here is a solution:

p = '23.4565.90'

def rreplace(string: str, find: str, replace: str, n_occurences: int) -> str:
    """
    Given a `string`, `find` and `replace` the first `n_occurences`
    found from the right of the string.
    """
    temp = string.rsplit(find, n_occurences)
    return replace.join(temp)

d = rreplace(string=p, find='.', replace='', n_occurences=p.count('.') - 1)

print(d)

>>> 23.456590

Answer 2

What about str.partition?

p = '23.4565.90'
a, b, c = p.partition('.')
print(a + b + c.replace('.', ''))

This would print: 23.456590

EDIT: the method is partition not separate
