Could someone explain to me what does "str" mean and what does it do? Thanks! :)

Answer 1

You can use str to type cast. and you can convert something (a float or integer) to string type.
e.g. lets say you have an integer type variable ...
>>> enrollment_number= 32
>>> str(enrollment_number)
'32'

try it on your idle.

Note: vice versa isn't possible for a string type variable. because strings cannot be converted into integer or float.
try this as well.
>>> iLike= 'Python'
>>> int(iLike)
you will get an error....

>>> float(iLike)
you will get an error again......

Hope this helps... Thank you and Happy Programming. :)

Answer 2

As far as I can tell, it converts one variable of any type into a string.
