The int() and float() functions perform variable conversions - also called "casting".
This allows you to change the datatype of a variable in cases where you may need to change the datatype because, say, a certain function only accepts or a certain operation only works properly with specific data types.
Consider this code:
num_int = 1 # datatype = integer
num_string = '1' # datatype = string
new_num_int = int(num_str) # datatype = integer (because it was cast/converted from a string to an integer)
For example:
print("There are " + 7 + " days in one week.")
will produce this error:
TypeError: must be str, not int
however, this:
print("There are " + str(7) + " days in one week.")
will not.

I hope that helps.
Stay safe and happy coding!
