Question

What is the difference between assert and if statement?

Answer 1

"assert" throw an AssertionError if the following condition is false, while "if" execute statement / block statements if the following condition is true, with the possibility to put an "else" (and/or "elif" -- else if) statement after...

"assert" is usually used for test purposes, while "if" is used to control the program flow.

"assert" is quite equivalent to something like:

if not condition:
raise AssertionError()

... and:

assert True # do nothing

... while:

assert False # stop program with an error and output the traceback until you catch the error with a try/except exception handler
