Question

On the assignments page it recommends python 2.5.4 instead of 3.0, but now the latest versions are 2.7.6 and 3.3.5. I'm assuming I should get 2.7.6 for the assignments? Thanks.

Answer 1

Answer 2

thanks

Answer 3

It was explained to me as 2.x.x will do fine for the course. 3.x was a revamped version of python. For example, Prof. John Guttag explains briefly in lec2 that 'raw_input' an 'input' are the options for user interaction. Only 'raw_input' is in Python V. 3.x while 2.x has both objects available. You both should be fine.

<= and >= are relational operators... a<=b checks if a is less than or equal to b
a>=b checks if a is greater than or equal to b
== is an assignment operator. a==b assigns the value of b to a
a+=b is used as shorthand means of writing a=a+b
