How to solve the following error in python: "IndexError: string index out of range"

Question

I have written a python code which gives the following error "IndexError: string index out of range"

Please tell me how to fix this error.

actuallink = 'http://www.exxonmobilperspectives.com'
slashcounter = 0
indexslash = 0
while slashcounter < 3:
    if(actuallink[indexslash] == '/'):
        slashcounter = slashcounter + 1
    indexslash = indexslash + 1
    PLink = actuallink[:indexslash - 1]

PS. When I change the link to anything else, it works perfectly

Answer 1

Something like

actuallink = 'http://www.exxonmobilperspectives.com'
endPoint = len(actuallink.split('/')) - 1
if endPoint > 0:
    slashcounter = 0
    indexslash = 0
    while slashcounter < endPoint:
        if(actuallink[indexslash] == '/'):
            slashcounter = slashcounter + 1
        indexslash = indexslash + 1
        PLink = actuallink[:indexslash]
