Today I meet this exercise:
What this code will output and why?
I expected to see 'd b c', but whet i run this program i was surprised. The output is [['d'], ['a', 'b', 'c'], ['a', 'b', 'c']].
Why is this code works this way?
What this code will output and why?
x = [[]]*3
x[0].append('a')
x[1].append('b')
x[2].append('c')
x[0]=['d']
print(x) I expected to see 'd b c', but whet i run this program i was surprised. The output is [['d'], ['a', 'b', 'c'], ['a', 'b', 'c']].
Why is this code works this way?
