Could someone give me tutorial on the following subjects in pythong: ???? - Slices - Escape sequences - len() - String Methods ? upper ? lower ? find ? replace ? count Then I would like to know ALL ways you can manipulate a user's input. ok also...when you have a string like "My foot" they are 2 seperate strings under one function or w/e...and is there any way to program in python...so that the computer can identify WHERE the space is...when print the words out seperately? so what im basically asking for this question is how do you slice a user's input? like make the output come out SLICED

look up the string module. and you can split "my foot" with the split function

Post subject:	RE:Strings

yes they need to write their fulll name so (First name) (Last name) but every time...the number of characters can be different but it is only 2 words under one raw input every time but i dont know how to slice that string cus its user input

Re: Strings

You're not manipulating anything while the user is entering input. But, once the user has entered input, is there any difference between a string generated like this:

Python:

string = raw_input()

and a string generated like this:

Python:

string = "John Doe"

Re: Strings

ok this is basically what its like

code:

string = raw_input ("Please enter your full name")

the user can now enter ANY name
now

code:

what would i enter here...so that W/E they inserted...can be split?

and yes dusk there is
because raw input could be any name
it isnt nessessarily going to be John Doe
so...how can you make it so that you can split a string...without knowing what the string will be? but it has 2 words and 1 space in between it...???

Re: Strings

Python:

namelength = 2 #Number of names we want (In this case, 2, as we just want a first and last name)
num_words = namelength + 1
while num_words > namelength:
string = raw_input("Enter your name: ")
string = string.split()
num_words = len(string)
print "out of loop"

Is this what you're looking for?

RE:Strings

i believe this is what he means

Python:

name = raw_input("Enter name")
name = str(name)
splitName = name.split()
print splitName

That's basically what I did, except my code checks to make sure the user has only entered two words, and no more. (It doesn't check if the user entered less than two words, but that's easily fixable.) I have a question about your code though. What is name = str(name) supposed to do? I believe raw_input() automatically treats input as a string.

That's funny, I don't get that. Are you using CPython?

that....is exactly what i mean
but when you split it...will it split it into 2 names?
???

It will split into the number of spaces that are present in the string. You will have to do a bit of checking to ensure that there are exactly two words. You'll probably want to look into the len() function.
