I've a pandas data frame which in its first column, the values are repeating every 5 rows like this:
ITEM VALUE
===== ======
item1 value1
item2 value2
item3 value3
item4 value4
item5 value5
item1 value6
item2 value7
item3 value8
item4 value9
item5 value10
i need to make a data frame like below with unique values from column 1 to use it as header and transpose every 5 records from column 2 under it. any easy way to do this using pandas? i checked all the pages in stackoverflow for data transposing using pandas but non of them was useful for this propose.
item1 item2 item3 item4 item5
====== ====== ====== ====== ======
value1 value2 value3 value4 value5
value6 value7 value8 value9 value10
Assign a group number and then pivot
it:
print (df.assign(group=df.index//5).pivot(index="group", values="VALUE", columns="ITEM"))
ITEM item1 item2 item3 item4 item5
group
0 value1 value2 value3 value4 value5
1 value6 value7 value8 value9 value10
