Does the str() function in Python will take all types of objects as parameters or only the Strings?

Question

>>> str("hello")
'hello'
>>> str([1,2,3])
'[1, 2, 3]'
>>> str({1,2,"hello"})
"{1, 2, 'hello'}"

what does it doing here?

Answer 1

str() turns stuff into strings. So [1, 2, 3] becomes '[1, 2, 3]' and {1, 2, 3} becomes '{1, 2, 3}'. 😉
