python - Why can I use a Boolean as list index?

Question

Can anyone help me understand below Python code?

In[41]: list_a = [1, 2, 3, 4]

In[42]: list_a[True]
Out[42]: 2

In[43]: list_a[False]
Out[43]: 1

Answer 1

True is interpreted as 1 so list_a[True] is equivalent to list_a[1] same for list_a[False] => list_a[0]
