Why do I hate Python?
I actually like Python, because it gives you a chance to prototype your idea really fast.
However, try to predict an output for the next simple examples?
class SimpleStructure(object):
x = []
obj1 = SimpleStructure()
obj1.x.append(1)
obj2 = SimpleStructure()
obj2.x.append(2)
print(obj1.x, obj2.x)
# Guess hereAny difference if we add a constructor?
class SimpleStructureWithConstructor(object):
def __init__(self):
self.x = []
obj1 = SimpleStructureWithConstructor()
obj1.x.append(1)
obj2 = SimpleStructureWithConstructor()
obj2.x.append(2)
print(obj1.x, obj2.x)
# Guess hereIt is not just an object, it is an instance. So instances and class variables, my friends.
Another example takes a peek at some unclear if statements
x=None
print("TRUE" if x else "FALSE")
print("TRUE" if x is not None else "FALSE")
x=0
print("TRUE" if x else "FALSE")
print("TRUE" if x > 0 else "FALSE")
x=''
print("TRUE" if x else "FALSE")
print("TRUE" if len(x) > 0 else "FALSE")
x=[]
print("TRUE" if x else "FALSE")
print("TRUE" if len(x) > 0 else "FALSE")
