How do I reverse a part (slice) of a list in Python?

Question

Why doesn\'t this work?

# to reverse a part of the string in place 
a = [1,2,3,4,5]
a[2:4] = reversed(a[2:4])  # This works!
a[2:4] = [0,0]             # Thi         


        

Answer 1

Just use the slice and reverse it.

a[2:4] = a[2:4][::-1]
