import fractions
f1 = fractions.Fraction[2, 3]
f2 = fractions.Fraction[3, 7]
print['{} + {} = {}'.format[f1, f2, f1 + f2]]
print['{} - {} = {}'.format[f1, f2, f1 - f2]]
print['{} * {} = {}'.format[f1, f2, f1 * f2]]
print['{} / {} = {}'.format[f1, f2, f1 / f2]]
2/3 + 3/7 = 23/21
2/3 - 3/7 = 5/21
2/3 * 3/7 = 2/7
2/3 / 3/7 = 14/9

I am trying to add two fractions in python
if input 1/4 + 1/4, I am expecting 1/2 result
I built a fraction class with an __add__ method for addition
from fractions import gcd
class fraction:
def __init__[self, numerator, denominator]:
self.num = numerator
self.deno = denominator
def __add__[self, other]:
self.sumOfn = self.num + other.num
self.sumOfd = gcd[self.deno,other.deno]
return[self.sumOfn, self.sumOfd]
print[fraction[1,4]+fraction[1,4]]
However I am getting 2,4 as output, which is actually 1/2, just not simplified. How could I fix that problem ?
from AddFraction import PlusFraction
class MinusFraction[PlusFraction]:
def __init__[self, fractions]:
super[].__init__[fractions]
def doSubtract[self]:
self.canoniseFraction[]
self.answer = self.new_numerators[0]
for count in range[1, len[self.new_numerators]]: self.answer -= self.new_numerators[count]
return {'numerator':self.answer, 'denominator':self.lcm}
from SubtractFraction import MinusFraction
numerators = [9, 3, 5, 7]
denominators = [2, 4, 12, 18]
fractions = {'numerators':numerators, 'denominators':denominators}
print['\n Solving:\n']
for numerator in fractions['numerators']: print['{:13d}'.format[numerator], end='']
print['{}{:>12}'.format['\n', ' '], end='']
for wasted in range[len[numerators]-1]: print['{}'.format['- + '], end='']
print['{:>1}'.format['-']]
for denominator in fractions['denominators']: print['{:13d}'.format[denominator], end='']
print['\n\n']
sub_fract = MinusFraction[fractions]
fraction = sub_fract.doSubtract[]
print['{:25d}'.format[fraction['numerator']]]
print['{:>25}'.format['Answer = -']]
print['{:25d}'.format[fraction['denominator']]]
print['\n\n']
