c

from math import sqrt
if c == '':

b = int(b)
result = sqrt(a * a + b * b)
print(f'The length of side C is: {result}' )
elif b == '':
a = int(a)
c = int(c)
result = sqrt(c * c - a * a)
print(f'The length of side B is {result}')
elif a == '':
b = int(b)
c = int(c)
result = sqrt((c * c) - (b * b))
print(f'The length of side A is {result}' )
else:
print('Please left an empty field to calculate it')
