you might consider getting the geany ide it auto indents and has about 20 different language it can be an ide for and all you have to do is get a compiler.
also you want to get to know Ubuntu and the terminal there are plenty of tutorials for those around.
picking a language
you will want to find a good language

This wiki is good for beginners, a lot of good resources and tutorials http://learnpython.pbwiki.com/HowToStart

[slavik]

you put in C++ but not C?

[bribaetz]

im know a lot about c like its really low level and hard for a first language.

The OP's opinion of C

[CptPicard]

i wrote this thread so new programmers would not end up where i did

Where did you end up? Why? What did you learn that you are applying here to make a better tutorial? :) Why are the other tutorials bad?

Anyway, welcome back man, I kinda missed you... kinda.. :)

yay my first functional program in python XD
can i ave opinions

loop = 0
choice = 0
while loop == 0:
##pycalc
##setting a vairiable for the loop
a = input("input a number:")
sign = raw_input("input +, /, *, -:")
b = input("input a number:")

if sign == "+":
choice = 1
if sign == "-":
choice = 2
if sign == "*":
choice = 3
if sign == "/":
choice = 4
if sign == "e":
choice = 5
if choice == 1:
c = a + b
print a, "+", b, "=", c

if choice == 2:
c = a - b
print a , "-", b, "=", c

if choice == 3:
c = a * b
print a, "*", b, "=", c

if choice == 4:
c = a / b
print a, "/", b, "=", c
if choice == 5:
loop = 0

[bribaetz]

is that really al everyone has for this thread

[CptPicard]

What is your point of using the "choice" variable? It's completely redundant. Just do the math already in the branch where you recognize the mathematical operation the user wants to perform by entering "+", "-", etc...

[bribaetz]

i guess i get what your saying i am really inexperienced at this but none the less it works but not well i guess

[CptPicard]

I suggest you go back to reading tutorials before writing them ;)

[bribaetz]

your right i thought it might be able to help but it probably confused anyone who tried reading it caused by my confusion

you can use dictionaries for all these if/elses


signs = { "+" : 4 , "-" : blah , blah ....}
choices = { }


you can use a while True (1) loop instead of specifying a loop flag.



while 1:
... do stuff
if choice in [ "q","Q"]; break # or exit
....

i haven't got that far yet
