Thank you very much everyone who helped answer. These all work as should and have been appendable. As no demonstrated below.
I am wanting to print working out of multiplication and addition.
import numpy as np
# [x, w] including bias
X = [[0.5, 0.15], [0.1, -0.3], [1, 0]]
in_str = 'in = '
for input in X:
substr = '('+str(input[0])+' x '+str(input[1])+') + '
in_str += substr
in_str = in_str[:-3]
print(in_str)
calcs = [x * y for x, y in X]
in_str = ' = '
for c in calcs:
substr = '('+str(c)+') + '
in_str += substr
in_str = in_str[:-3]
print(in_str)
ans = sum([x * y for x, y in X])
print(' = ' + str(ans))
Output:
in = (0.5 x 0.15) + (0.1 x -0.3) + (1 x 0)
= (0.075) + (-0.03) + (0)
= 0.045
Use list comprehension:
ans=sum([x*y for x,y in X])
