What is mean of == in python

Answer 1

compares to,
compares two value and returns true if they have equal values regardless of type

Answer 2

Brains is right but I think that "regardless of type" might be misunderstood. This does not mean that '5' == 5 which will return False

Answer 3

== means 'is set to' (equivalence)
= means 'is' (identity)
