A little Calculator writed in Python.

SpeedVin · 2009-09-24 15:48:46

Hello.
I write (with some help-Thanks Xyne) a very simple calculator.
It only need python package to work.
Here it is.
It could do base thing's.

 
#!/usr/bin/env python
# -*- coding: utf-8 -*-
 
number1 = int(raw_input('Write a number: '))
number2 = int(raw_input('Write a number nr.2: '))
znak = raw_input('What to do?')
if znak == '+':
 print number1 + number2
elif znak == '-':
 print number1 - number2
elif znak == '*':
 print number1 * number2
elif znak == '/':
 print number1 / number2
elif znak == '**':
 print number1 ** number2
elif znak == '//':
 print number1 // number2
else:
 print "I don't know what to do with " + znak

Any suggestions or ideas?

Why not just 'python' in terminal?

$ python
>>> 2+2
4
>>> 2*2
4
>>> 2/2
1
>>> 2**2
4

Sorry if I misunderstood...

How about:

alias calc='bc -l <<<'

$ calc 2+2

Or pacman -S calc.

Update
Calculator now can floor division.

#!/usr/bin/env python
# -*- coding: utf-8 -*-
 
number1 = int(raw_input('Write a number: '))
number2 = int(raw_input('Write a number nr.2: '))
znak = raw_input('What to do?')
if znak == '+':
 print number1 + number2
elif znak == '-':
 print number1 - number2
elif znak == '*':
 print number1 * number2
elif znak == '/':
 print number1 / number2
elif znak == '**':
 print number1 ** number2
elif znak == '//':
 print number1 // number2
else:
 print "I don't know what to do with " + znak

speedvin, your code works and it is always good to learn a language and start with such calc program gives the inner of structured programming. I have this simple function in .bashrc and serves the purpose.

function calc() { echo "scale=4;$*" | bc; }

calc 10/3+6 gives 9.0303

Thanks kgas
I updated calc for a help message (run it with -h).
Anyone can find current code at my github site.
