Convert string to modified digit

Question

I have the following numbers, which I want to convert:

'2.44' --> '2.44'
'12.83' --> '2.83'
'121.834' --> '1.83'

In other words, I want 1 digit to the left of the decimal point and two digits to the right. What would be the best way to do this? My current method is using:

number = '41.33'
index = number.index('.')
result = number[index-1] + '.' + number[index+1:index+3]

Is there a better, cleaner way to do this?

Answer 1

result = number[index - 1: index + 3]

that is all
