I sorted my data frame by date and then rotated the data frame, but the rotated data frame is not in the order that I asked before.
df1 = df1.sort_values (by = (& # 39; DATE & # 39;))
df2 = df1.pivot (index = CL CLIENT,, columns = (VIS VISIT_N,), values = D DATE #)
Are there any parameters in Pivot that can help maintain the order? Can you guess?
