Print "user_num1 is negative." if user_num1 is less than 0. End with newline. Assign user_num2 with 1 if user_num2 is greater than 12. Otherwise, print "user_num2 is less than or equal to 12.". End with newline.
My code:
user_num1 = int(input())user_num2 = int(input())
if user_num1 < 0: print("user_num1 is negative.")
if user_num2 > 12: user_num2 == 1
else: print("user_num2 is less than or equal to 12.") print('user_num2 is', user_num2)
When the input is 0 and 13 my output for user_num2 is 13 and it should be 1. I don't know what I'm doing wrong.

You are required to write a code that requests the user to enter three integer coefficients: a, b, and c in this order. Next, the user is requested to enter the equation degree: 1 for a linear equation and 2 for a quadratic equation. If the user enters an equation degree other than 1 or 2, the program must output Invalid. Based on the equation type, the program will process the coefficients and provide outputs as described below:
First Scenario: Linear Equation
When a linear equation is selected, the coefficient a is ignored and the equation format becomes:
y=bx+c
The program should check the slope of the line and accordingly print the values of the x-intercept, the y-intercept, and the line direction with respect to the x-axis each on a separate line. We have four possibilities:
Slope is positive (i.e. b > 0): x-intercept = −cb, y-intercept = c, direction is UpwardSlope is negative (i.e. b < 0): x-intercept = −cb, y-intercept = c, direction is DownwardSlope is zero (i.e. b = 0)…
