Newb: Simple Explicit Formula - Duplicitous - May-05-2017 I am incredibly new to python (I'm officially on my fourth day of learning) and as a test of what I've learned so far, I wanted to make a simple Explicit Formula calculator. The formula is: a(n) = a(1) + (n - 1)d This is what I came up with: aone = raw_input("Enter the first term: ") n = raw_input("Enter the n term: ") d = raw_input("Enter the difference: ") answer = n - 1 answer = answer * d answer = answer + aone print answerThe printout from the terminal is this: I'm sorry if I look like the biggest imbecile on the planet, but this is beyond me at this stage in my coding abilities. Sorry. :(
RE: Newb: Simple Explicit Formula - buran - May-05-2017 raw_input (in Python2) and input (the equivalent in Python3) return str . you need to convert that to int or float to use in calculationsPython 2.7.12 (default, Nov 19 2016, 06:48:10) [GCC 5.4.0 20160609] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> x = raw_input('some number: ') some number: 3 >>> x '3' >>> type(x) <type 'str'> >>> int(x) 3 >>> float(x) 3.0 |
