Python
Consider the following code:
funs = [lambda: i for i in range(3)]
print([f() for f in funs])The result it [2,2,2].
funs = [lambda i=i:i for i in range(3)]
print([f() for f in funs])or
funs = (lambda: i for i in range(3))
print([f() for f in funs])The result is [0,1,2].
def f(n, lst=[]):
lst.append(n)
return lst
print(f(1), f(2))The result is [1,2], [1,2].
