How can I create an array/list of dictionaries in python?

Question

I have a dictionary as follows:

{'A':0,'C':0,'G':0,'T':0} 

I want to create an array with many dictionaries in it, as follows:

[{'A':0,'C':0,'G':0,'T':0},{'A':0,'C':0,'G':0,'T':0},{'A':0,'C':0,'G':0,'T':0},...] 

This is my code:

weightMatrix = [] for k in range(motifWidth):     weightMatrix[k] = {'A':0,'C':0,'G':0,'T':0} 

But of course it isn't working. Can someone give me a hint? Thanks.

Answer 1

This is how I did it and it works:

dictlist = [dict() for x in range(n)] 

It gives you a list of n empty dictionaries.

Answer 2

weightMatrix = [{'A':0,'C':0,'G':0,'T':0} for k in range(motifWidth)]
