Python 'iff' HELP

[TechFnatic]

Hey im doing some exercises in python and I came across the word 'iff' in some of them, I know what the 'if' function is and what it does but I'm just confused as to why there is an extra 'f' added to the end of it?

 

Thank you!

examples

def iif(condition,resultiftrue,resultiffalse):    if condition:return resultiftrue    else: return resultiffalse

• x < y returns True iff x is strictly less than y.
• x > y returns true iff x is strictly greater than y.
• x <= y returns True iff x is less than or equal to y.
• x >= y returns True iff x is greater than or equal to y.
• x == y returns True iff x is equal to y.
• x != y returns True iff x is not equal to y.

its just a term used in python really  uve got iff and ifs and iifs

 

Python uses lexicographic order and its bad to rely on floating point numbers

iff with the extra 'f' means "if and only if". https://en.wikipedia.org/wiki/If_and_only_if

Sorry to bother again, but is iff not recognized by Python but rather just an abbreviation for 'if used for instruction?

( was already in my first post )

 

but thats all it to there on iff   try reading my first post and try understanding hehe, thats all there to it

dunno if this helps u but il post it for u anyway so u got an example of python rly, u dont need to force urself to use iffs instead of if ect

 

import optparse

parser = optparse.OptionParser('usage %prog -H'+\

'<target host> -p <targetport>')

parser.add_option(*-H*. dest='tgtHost'. type='string'. \

help='specify target host')

parser.add_option('-p'. dest='tgtPort'. type='int' . \

help='specify target port')

(options. args) = parser.parse_args()

tgtHost = options.tgtHost

tgtPort = options.tgtPort

if (tgtHost == None | {tgtPort == None}:

print parser.usage

exit(0)

Did I miss something? I thought this was an innocent question asking about the meaning of iff...

Please use code tags when posting code. And just to add, optparse is deprecated since 2.7 and 3.2 so you should be using argparse instead if possible.

was just joking around a lil ofc( most ppl appreciate the jokes actually ;x )

 

second i dont know any code tags from forums because i dont bother with forums normally this is basicly my first forum experience haha

That's fine, just use them from now on as it makes code easier to read. It will format the text and uses some basic syntax highlighting.

# This is an exampleif x < 10:    print(x)else:    print("Not less than 10")

For really long pieces of code, it's best to also use spoiler tags or just link to the code uploaded somewhere else.

 

# A lot of code goes here...
