python remove string from string given location

Question

I have a list of IDs that I wish to extract, specifically for ID the intermediate values.

For example, the 1st ID is : garden/trade.FX.fwd/nyk12523adn

I wish to remove the values 'garden/', and '/nky12523adn', perhaps using string.replace()...

How might I do that efficiently? The starting logic would be to

string.find('/'), to get the location
then remove the prefix for the first '/', and suffix for the 2nd '/'

Is there an efficient way to do this?

you can also use .split() method

The split() method splits a string into a list.

You can specify the separator, default separator is any whitespace.

Syntax
string.split(separator, maxsplit)

id = "garden/trade.FX.fwd/nyk12523adn"
print (id.split('/')[1])

output:

trade.FX.fwd

if you want to use .find() function:

id = "garden/trade.FX.fwd/nyk12523adn"

idx_start = id.find('/') # find index of first '/'
idx_end = id.find('/',idx_start + 1) # find index of second '/'

print (id[idx_start+1:idx_end]) # use list slicing

output :

trade.FX.fwd
