variable declaration

[Alexander]

Hello All!

I'am novice in python, and I find one very bad thing (from my point of view) in
language. There is no keyword or syntax to declare variable, like 'var' in
Pascal, or special syntax in C. It can cause very ugly errors,like this:

epsilon=0
S=0
while epsilon<10:
  S=S+epsilon
  epselon=epsilon+1
print S

It will print zero, and it is not easy to find such a bug!

Even Visual Basic have 'Option Explicit' keyword! May be, python also have such
a feature, I just don't know about it?
