将单词列表转换为先前在Python（2.7.1）中分配的数字列表

Question

I have a code "aaabbbcccdddeee" that I split up into 3 letter words (such as 'aaa' , 'bbb' , 'ccc' . . . and so on) and assigned a number value to them using

d=dict(zip(('aaa','bbb','ccc','ddd','eee'),('123','234','345','456','567')))

If random sequence that has

random='aaabbbdddccceeedddbbbaaaeeeccc'

How can I create a list that converts the random sequence into a list composed of the number values that were assigned previously

Example:

random='aaabbbdddccceeedddbbbaaaeeeccc'

to produce

'123','234','456','345','567','456','234','123','567','345'

Answer 1

mapping = <your dictionary>
instr = <your data>
result = [mapping[instr[i:i+3] ] for i in range(0, len(instr), 3)   ]
