There are my lists:
i1,i2,i3,i4,i5 = [],[],[],[],[]
and I need the string "test" to be appended to each list. How can I do that?
I thought about using a loop but couldn't manage to do that.
Are there any other ways to append to all the five lists?


easy busy
i1,i2,i3,i4,i5 = 5*[['test']]

how can we write this single statement code into multiple lines?
I can understand only for loop written in multiple lines. Anyone, please break this code into multiple line code.
amp.append([amp[i] for i in ida])

By a for loop:
l = []
for i in ida:
l.append(amp[i])
amp.append(l)
