I have a list like
source = [{'TGA': [0, 1, 0, 0], 'AAC': [0, 0, 0, 1], 'GAA': [0, 0, 1, 0],
'GTG': [1, 0, 0, 0]},{'TGA': [0, 1, 0, 0], 'AAC': [0, 0, 0, 1],
'GAA': [0, 0, 1, 0], 'GTG': [1, 0, 0, 0]} ]
I need to sum every digit in list column:
pandas.DataFrame(source)
AAC GAA GTG TGA
0 [0, 0, 0, 1] [0, 0, 1, 0] [1, 0, 0, 0] [0, 1, 0, 0]
1 [0, 0, 0, 1] [0, 0, 1, 0] [1, 0, 0, 0] [0, 1, 0, 0]`
And in final:
AAC GAA GTG TGA
sum [0, 0, 0, 2 ] [0, 0, 2, 0] [2, 0, 0, 0] [0, 2, 0, 0]
How can I do this?
You can use this to sum a list of dict of list:
source = [{'TGA': [0, 1, 0, 0], 'AAC': [0, 0, 0, 1], 'GAA': [0, 0, 1, 0],
'GTG': [1, 0, 0, 0]},{'TGA': [0, 1, 0, 0], 'AAC': [0, 0, 0, 1],
'GAA': [0, 0, 1, 0], 'GTG': [1, 0, 0, 0]} ]
res = {}
for d in source:
for key,value in d.items():
if key not in res:
res[key] = value
else:
res[key] = [x+y for x,y in zip(res[key],value) ]
print res
You can easily change the entries into numpy.array
s, then sum:
import numpy as np
>> df.applymap(np.array).sum()
AAC [0, 0, 0, 2]
GAA [0, 0, 2, 0]
GTG [2, 0, 0, 0]
TGA [0, 2, 0, 0]
