Remove everything from before the :-CodePudding

I need to remove everything before the :

Active Scanning: Scanning IP Blocks

I just need to keep the Scanning IP Blocks

val = "Active Scanning: Scanning IP Blocks"

pos = val.rfind(':')
if pos >= 0:
    val = val[:pos]

print(val)

But I'm getting the everything before the :

CodePudding user response：

[:pos] means 0 to pos which you don't want. write [pos 1:] what will give you pos to the end of the string.

val = "Active Scanning: Scanning IP Blocks"

pos = val.rfind(':')
if pos >= 0:
    val = val[pos 1:]

print(val)

CodePudding user response：

You can try:

>>> import re
>>> val = "Active Scanning: Scanning IP Blocks"
>>> re.sub(r'^.*?:', '', val)
' Scanning IP Blocks'

CodePudding user response：

string[startIndex:endIndex] that is how it works. So you have to :

val = "Active Scanning: Scanning IP Blocks"

pos = val.rfind(':')
if pos >= 0:
    val = val[pos 1:]

print(val)

or you can use split()

val = "Active Scanning: Scanning IP Blocks"

pos = val.rfind(':')
if pos >= 0:
    val = val.split(":")[1]

print(val)
