Python split array and check the 0 index if the same and join it

Question

I have an array looks like:

['varyasyon__in=27', 'varyasyon__in=25', 'varyasyon__in=1']

and I want to split every value on = and join it to be a string like:

varyasyon__in=27,25,1

Answer 1

Can you try the following:

f"varyasyon__in={','.join([val.split('=')[1] for val in data])}"

Output:

varyasyon__in=27,25,1

Answer 2

?ommon solution with dictionary:

lst = ['varyasyon__in=27', 'varyasyon__in=25', 'varyasyon__in=1']

d = {}
for i in lst:
    d.setdefault(i.split('=')[0], set()).add(i.split('=')[1])
    
print(d)

Output:

{'varyasyon__in': {'27', '25', '1'}}
