x will always be a string.
you can convert to whatever is needed.
Example:

orig = input("enter a float")
print(f"orig: {orig}, type orig: {type(orig)}")
afloat = float(orig)
print(f"afloat: {afloat}, type afloat: {type(afloat)}")

Output:
enter a float: 123.45
orig: 123.45, type orig: <class 'str'>
afloat: 123.45, type afloat: <class 'float'>
