Hi all,
I was playing with Python tonight and created a simple program that outputs
numbers counting up then counting down all on the same terminal line. The code
is as follows:
#------------------------------------------------------------
a = 320000 #number to count up to
for i in range (a):
print i, '\r',
for i in range ((a-1),0,-1):
print i, '\r',
#------------------------------------------------------------
It works as desired. However, I was trying to figure out a way to make it more
concise but
cannot see a way since the 'range' parameters must be integers (no functions
allowed?).
If the functions return integers that's fine.
for i in range(int('0'), int('5'), int('1')):print(i)
0
1
2
3
4
Anyone see a way to simplify it?
Well you could have:-
a = 5
for start, stop, step in ((0, a, 1), (a-1, 0, -1)):
for i in range(start, stop, step):
print(i)
0
1
2
3
4
4
3
2
1
But is it actually simpler? I find your original code far easier to
read so quite frankly I'd leave it as is. If it ain't broke, don't fix
it :)
