1. starting Python from IdieIdle is a python shell,shell meaning "shell", which is basically a way of interacting with the program by entering it. Windows like the cmd window, like the Black Command window of Linux, are all shells and can be used to give commands to the operating system. Similarly, you can use the idle shell to interact with the Pytho. >>> This prompt means: Python is ready, waiting for the Python command to be entered;baishuchaodemacbook-pro:~ xcn$ Python3.5python 3.5.2rc1 (V3.

representing the distance from the left arm, and a positive right arm; G on behalf of a few weights, you want to make this balance to maintain a number of methods, require all weights used up. train of Thought DP[I][J] dp[i][j], I I for the number of weights placed, J J for the equilibrium state, when the j=0 j=0 balance. But this definition of J J is likely to be negative and is not allowed when used as an array subscript, so we calculate that the maximum of the left or right of the Libra is 7
