How to import a single function from a Python module?
You can use the "from module import function" statement to import a specific function from a Python module. For example, if you want to import the sin function from the math library without importing any other function, you can do it as follows:
>>> from math import sin >>> sin(0) 0.0
Note that you don't have to prefix sin with "math." as only sin has been imported and not math. Also you can alias imported functions. For example,
>>> from math import cos as cosine >>> cosine(0) 1.0
