Python Lists and Dictionaries

Hey, I have a result in my code as set of dictionaries inside a List as seen here:
[(1, 100000), (2, 200000), (3, 300000)]
So if i want to make variables(lets say a, b and c) which is equal to
a = 1 has 100000
b=  2 has  200000
c= 3 has  300000
how would i go about doing this. This is what i think it should contain:
for i in range(0, len(result)):

    a+=str(i[0][0]) + ' has' + str(i[0][1])

    b+=str(i[1][0]) + ' has ' + str(i[1][1])

    c+=str(i[2][0]) + ' has ' + str(i[2][1])

        print a

        print b

        print c

That's a list of tuples, not dictionaries.

You don't need a loop in this case:
result = [(1, 100000), (2, 200000), (3, 300000)]

a = str(result[0][0]) + ' has ' + str(result[0][1])

b = str(result[1][0]) + ' has ' + str(result[1][1])

c = str(result[2][0]) + ' has ' + str(result[2][1])

print a

print b

print c
 

# using a loop:

for i,j in result:

  print i,'has',j

or, you could even do:

a, b, c = [(1, 100000), (2, 200000), (3, 300000)]

print a
print b
print c

You could do the same with shorter (but more complex) code:
result = [(1, 100000), (2, 200000), (3, 300000)]

a,b,c = map(lambda t:'%s has %s'%t,result)

print a

print b

print c
