Is there any python keyword for replacing last decimal point from a number string-CodePudding

I am trying to replace the decimal point with null except last decimal eg:

number="123.34.56.04"

I need to delete 123.34.56 and need to get the final answer as .04 anyone, please help me to out of this. Thanks in advance

Try splitting the number using the dot as a separator and then get the last value. The number variable needs to be a string:

number = "123.34.56.04"
list1 = number.split(".")
last_number = list1[-1] # to get the last value

CodePudding user response：

You can use .rpartition('.') to split the string by the right most '.':

>>> number="123.34.56.04"
>>> number.rpartition('.')
('123.34.56', '.', '04')

Then use .join to reform the number:

>>> ''.join(number.rpartition('.')[1:])
'.04'

This works as expected even if there is no '.':

>>> ''.join('1234'.rpartition('.')[1:])
'1234'
