enter image description here

a, b, c = input() 
d = b*b - 4ac 
if d > 0:
  print(+sqrt(d)-b/(2a))
  print(-sqrt(d)-b/(2a)) 
else:
print("No real roots")

This question is from an online python practice sample. I am new to learning python and also tried writing the same program in the code editor and it says no many syntax errors. Help!

    Hi, There are multiple mistakes in the code you shared. You are directly using algebraic notations like "4ac" which should actually be "4 * a * c". Please start with simple Hello World programs at first and then move on to more complex ones. – Swastik Mohapatra Feb 11 '21 at 08:33

Here would be a running solution, but as the other user in the command pointed out it would be better to start slowly and understand the concepts better

try:
    inputs=(input("Type in 3 consecutive numbers seperated with spaces:").split() )
    a,b,c = map(int, inputs)
except ValueError:
    print("This is not a whole number.")

d = b*b - 4*a*c 
if d > 0:
    print(+sqrt(d)-b/(2*a))
    print(-sqrt(d)-b/(2*a)) 
else:
    print("No real roots")

  • then you need to convert your a,b,c - variables to integer values - because the input() funciton only returns a string – T1Berger Feb 11 '21 at 09:05
  • Can we use this for input "a, b, c = map(int, input("Enter three values: ").split())" – aayushkrm Feb 11 '21 at 09:09

After few tweaks, this program works as intended.

a, b, c = map(int, input("Enter three values: ").split())
d = b*b - 4*a*c
if d > 0:
    print(+sqrt(d)-b/(2*a))
    print(-sqrt(d)-b/(2*a))
else:
    print("No real roots")
