NUF Programming Club's Learning Corner

white hat? perhaps you can find some stuff in /r/opendirectories or something in reddit. I've got some book and tutorial there. But never feel the need to read it, so it lays abandoned somewhere.

 

I second this.

Guess I'll be keeping an eye on this thread.

 

Learn to code first.

Later visit www.hackthissite.org

Take their lessons.

 

I know how to code. (studied IT)^^

 

Check the link then. Welcome to the Dark Side. &_&

 

What is &_& ? I've see it appearing a lot more lately, enlighten this traveller.

 

I just made it up a little while ago. I was frustrated with not getting some emotes, so I decided to share my pain.

It means: whatever you think it means.

Or it can mean fire eyes. _

 

I see, I had a quick google while I was waiting

So look out not to get into any misunderstanding

 

@_@ Oh well.

 

(python)
How do you get to know whether a character in string A is in string B? I just need to know if at least one character is common in both of them.
for eg.
x = 'asdf'
y = 'fghj'
In this, we know that 'f ' is common. How to make a program to find out whether x and y have a character in common?
(Since I don't need to to find the substring x in y or vice versa, I cannot use in or .find , right?)

 

Except a character is a substring in python. So the simplest way is to iterate through x and see whether the current character is in y, in which case, both in and find() are viable.

 

Code:

set(x).intersection(y)

 

Neat. I didn't know Python has goodies for set operations. Thank you.

 

(sorry for the late reply)
hmm...when you just do x in y, the whole substring x is searched in the same sequence in y. But I only wanted one character. I guess loop is the best option. Here is what I wrote (I have just started functions; I originally wanted this for writing a function):
def isIn(x, y):
for i in x:
if i in y:
return True
return False # defined the function
w = 'qwefsdsav'
q = 'asdaugfwq'
print(isIn(w, q))
True

Too simple to be true. But sadly I am a novice. I will have to stick to loops right now :/
thanks

 

I know, right? This is why Python has a wide fanbase. It's simple and it comes equipped with lots of nice things.

Also, I think your solution is good enough. However, @noisypixy showed us a cleaner one. Note that according to Python's docs, you should use frozensets instead of sets because set() was deprecated in 2.6.

 

It's the sets module that was deprecated, not the set/frozenset builtins.

 

Yeah, I see it now. Thanks.

 

this thread had no replies for over a month :/

 

I know, right? >: I'm still waiting for my guide....

 

What guide?
