Hey yury hows it going?
Python is fairly smart at figuring out if you want to do something
with a variable or not. I dont know if you know but you can use the if
statement very loosely. For example:
foo = None
# None = False
if(foo):
print 'yes';
>>
foo = []
# [] = False
if(foo):
print 'yes';
>>
foo = [1,2,3]
# [1,2, 3] == True
if(foo):
print 'yes';
>> yes
foo = 5
# 5 == True
if(foo):
print 'yes';
>> yes
foo = 'test'
# 'test' == True
if(foo):
print 'yes';
>> yes
foo = ''
# '' == False
if(foo):
print 'yes';
>> yes
