data_copy=data[:] #here you copy list data to data_copy
for i in range(len(data_copy)): #starting 1st loop
for j in range(0,len(data_copy)-i-1): #starting 2nd loop
if data_copy[j] > data_copy[j+1]: # conditions for bubble sorting
data_copy[j],data_copy[j+1]=data_copy[j+1],data_copy[j] #swapping elements
hope it helps...
