Play with Python 2
perhaps you still relish one or two loops
open a terminal and start the interpreter
set the variable
>>> a = 0
and copy the yellow colored into the interpreter
>>> while a < 10 :
a += 1
print (a)
<return> 2 times
to say today you have learned and execute Fibonacci in Python
( maybe you a hacker? )
set the variables
>>> a = 0
>>> b = 1
and copy the yellow colored into the interpreter
>>> count = 0
max_count = 20
while count < max_count:
count = count + 1
#
old_a = a
old_b = b
a = old_b
b = old_a + old_b
#
#
print (old_a),
<return> 2 times
and copy it into the interpreter once more
>>> count = 0
max_count = 20
while count < max_count:
count = count + 1
#
old_a = a
old_b = b
a = old_b
b = old_a + old_b
#
#
print (old_a),
<return> 2 times
the variables (or values to be assigned to them)
can be accessed anytime
>>> a
<return>
>>> b
<return>
a permanent background loop would thus provide constant values
have phun ;-)

Ok, took me a minute to figure out the browser's interpretation of tab. I'm a little bit sad about what the standard browser behavior has done to indentation. (and linguistic formatting in general) | |

By asking you to copy and paste his sample code, ulysses misses the opportunity to mention/explain that the python language uses tab indentation to express (some would say "hide") block structure in iterated and other conditionally executed code. I only found this out by typing in the text of the code long-hand: the interpreter kept complaining about the absence of indentation in what I had typed, and would only be placated by my inserting tabs, rather than spaces. On the other hand, I only discovered this by working my way through the tutorial ... |
