Error: string index out of range

I coded the python function given below:

def processstring(string):
    gtkname=""
    if string[0]=="/":
        i=1
        while(string[i]!="/"):
            if i==len(string):
                break
            gtkname=gtkname+string[i]
            i=i+1
        return gtkname
    return string

when I execute the code it gives me the following error:

while(string[i]!="/"):
IndexError: string index out of range.

I don't know why is it giving this error.

You are not manipulating the iteration on string characters in a proper way

def processstring(string):
    if string[0]=="/":
        return string[1:string.find("/",1)]
    return string

Python give us ways to not using direct iteration on index of a list

The condition is causing the error: while string[i] != "/":

After you increment i, you check that condition before you check if i == len(string): to break the loop. Move that check to the end of the loop:

    while(string[i]!="/"):
        gtkname=gtkname+string[i]
        i=i+1
        if i==len(string):
            break
