Python string error

[survuvi]

Why I get the following error?

from PythonInterface import Python

print(Python.str("Hello Mojo!!")[0:10])

error: Expression [28]:22:17: 'Python' value has no attribute 'str'
print(Python.str("Hello Mojo!!")[0:10])

Accordingly to Mojo documentation Python interface has not strmethod, so it is necessary using the builtins python package.
Here an example, using the str and slice functions from python to process the string. Also the print function from builtins is required to handle str type correctly:

from PythonInterface import Python
let builtins = Python.import_module("builtins")
let x = builtins.str("Hello Mojo!!")
let slicing = builtins.slice(10)
builtins.print(x[slicing])
