Question

lesson 1.4 Part 2
I'm having trouble with how to code the answer: 7+9=16 sqrt 4*2=8. any help is greatly appreciated

Answer 1

is this part of python MOOC or something else?

Answer 2

it's part of 6.189 Homework 1 Exercise 1.4
I hope I'm working on the right assignments

Answer 3

yes, it's part of the MOOC... sorry.

Answer 4

hm, I seem to have different numbers/task but if you question is python code to print those results
then just simply use print:

print 7+9
print 4*2

Answer 5

Thanks @zlatandebian I might have printed off the wrong assignments

Answer 6

No problem, and just in case you needed sqrt of 4 to get 16, then you just put two asterix as:

print 4**2

Answer 7

Your the best, Thanks! Now to figure out this raw_input stuff (exercise 1.5 User Input). being a noob programmer is tough -lol!

Answer 8

hm, I am noob also ;) well I don't think we need to do 1.5 at first week. Anyway its fairly straightforward looking to me. Just assign some variables with raw_input and print it out.

P.S. if you need to get 4 from 16 then just use negative number as: print 16**(-2). Cheers

Answer 9

@ zlatandebian you've been a lifesaver.

I did the following for 1.5 exercise
e = raw_input ("Enter your first name?")
f = raw_input ("Enter your last name?")
g = raw_input ("Enter your date of birth")
print e + + f + + g
sadly this is what I'm getting:
>>> ================================ RESTART ================================
>>>
Enter your first name?john
Enter your last name?doe
Enter your date of birth1/1/1900
johndoe1/1/1900
>>>

Answer 10

if you need it to be in one line you must have spaces between (and also there is no need to use two pluses, one is ok). so just add empty spaces ( hint: use " ")

if you want to put it one below another then you need 3 print statements

print e
print f
print g

Answer 11

awesome! Thanks again!!

Answer 12

do you know where/how we turn in our homework?

Answer 13

I don't know about that really (I do not know if we even need to turn our homework :-/). Maybe @MOOC-E could tell us more?

Answer 14

sounds good. I'll leave you alone now :) and wait for a response from @MOOC-E

Answer 15

Just to share flexibility of python - while I looked at raw_input assignment I noticed that you could nice print one line as follow:

print x, y, z

Yay, Monty! :)

Answer 16

Hey @nsite7, no you don't submit homework in this course. Mostly you can tell if it works or it doesn't in the Python interpreter. Feel free to post code on OpenStudy for feedback from your fellow learners.

Answer 17

@ zlatandebian - Cool!
@MOOC-E - Thanks, I'm really looking forward to learning Python and hopefully not having to bother everyone so much in the future.

Answer 18

A couple of terminology corrections: 4 squared is programmed 4**2. The square root of 4 is programmed 4**.5 or

import math
math.sqrt( 4 )

FYI, raw_input() returns a string. If you want to use it for numbers:

foo = float( raw_input( "Enter a number: " ) )
