Hi, I am learning Python. I wrote a simple two loops with if and else. Here is my code: for i in range(N): ....x = x_val[i].dot(self.w) ....x =np.max(x) ....s = np.exp(x) ....for y in range(M): ........if y == y_value[i]: ............res = s[y] + 1 ........else: ............res = s[y] I would like to combine if and else on one line for saving space. ....for y in range(M): ........res = s[y] + 1 if y == y_value[i] else res = s[y] But the syntaxError happens: cannot assign to condition expression. Who knows the reason? Thanks

Question
Hi, I am learning Python. I wrote a simple two loops with if and else.
Here is my code:
for i in range(N):
....x = x_val[i].dot(self.w)
....x =np.max(x)
....s = np.exp(x)
....for y in range(M):
........if y == y_value[i]:
............res = s[y] + 1
........else:
............res = s[y]
I would like to combine if and else on one line for saving space.
....for y in range(M):
........res = s[y] + 1 if y == y_value[i] else res = s[y]
But the syntaxError happens: cannot assign to condition expression.
Who knows the reason? Thanks
