In the above example, thetranspose()function returns a new array with the axes switched. In the case of the 2D array like our list, the rows and columns have been swapped. You will notice that all three examples return the same results, but in slightly different structures. Therefore, sele...
DataFrame.nlargest(n, columns[, keep]) #Get the rows of a DataFrame sorted by the n largest values of columns. DataFrame.nsmallest(n, columns[, keep]) #Get the rows of a DataFrame sorted by the n smallest values of columns. DataFrame.swaplevel([i, j, axis]) #Swap levels i and j ...

SkipBlanks:=False, Transpose:=False 这次,我们可以用上面的方法得到xlPasteAll、xlMultiply等常量的值,将上面的代码python化即可; 利用这个方法,我们还可以很轻易得到某一列的最后一行的行号,比如A列的,可以这样写: max_rowA=sht.cells(sht.Rows.Count,1).End(-4162).Row ...
