Parameters参数 **by:**mapping, function, label, or list of labels Used to determine the groups for the groupby. Ifbyis a function, it’s called on each value of the object’s index. If a dict or Series is passed, the Series or dict VALUES will be used to determine the groups (the...
if we use any arithmetic operator (+, -, /, etc.) along with the equal to operator then it will perform the arithmetic operation on the given variable and then assign the resulting value to that variable itself.

For example, we can combine 1,000 jobs into one before we submit it to unless we are required to solve each job in real time (ie. if you implement a REST API server, we shouldn't do in this way).x * xmultiprocessingPool Share Improve this answer Follow edited Jan 25, 2014 at 11...
