Extend multiple elements in one line iteration [duplicate]

Image
4 This question already has an answer here: List comprehension version of “extend” [duplicate] 1 answer For A=[1,2,3] I would like to get B=['r1','t1','r2','t2','r3','t3'] I know it is easy to get ['r1','r2','r3'] by ['r'+str(k) for k in A] How could I get B by one line loop as I showed above? Many thanks. python list loops iteration share | improve this question asked Nov 12 at 15:08 Xiaojian Chen 42 5
