Python closures and late binding in lambdas

# ======================================================================
# Q: What is a closure? What does the following code print?
#
# The lambdas close over the variable i, not its value at the time of creation
# (late binding). When they are called, i is 2. Fix: lambda i=i: i, which binds
# the value as a default argument, or functools.partial.
# ======================================================================

funcs = [lambda: i for i in range(3)]
print([f() for f in funcs])   # [2, 2, 2]
