You are now writing a program to ask for user's input in determine a number is a divisor of a user-defined number. # Assume there are two variables called "num" and "u_divisor" that # store the integer that a user inserted. # You can safely assume the user will only insert numbers without the dot # or comma, and the user will not enter o for "u_divisor". num = input("Please insert the dividend.") u_divisor = input("Please insert the divisor") if : print(u_divisor, "is not a divisor of", num + ".") else: print(u_divisor, "is a divisor of", num + ".") Which of the following is/are the correct condition(s) to replace the part in the above code to correctly achieve the purpose? (float(num) / float(u_divisor)) != int(float(num) / float(u_divisor)) not (float(num) % float(u_divisor) = 0) (float(num) // float(u_divisor)) != (float(num) / float(u_divisor)) float(num // u_divisor) != float(num / u_divisor) You are going to write a program to determine the correctness of a variable name. # Assume there is a string variable called "var" storing the # intended name for a Python variable. # You can safely assume your user will only enter alphabets and numbers. var = input("Insert the name of variable.") Which of the following is/are wrong in achieving the purpose? if var[0] != "1234567890": print("This is a good variable name.") else: print("You cannot use this is as a variable name.") if var[@] in 1234567890: print("You cannot use this is as a variable name.") else: print("This is a good variable name.") if var[0] == True: print("This is a good variable name.") else: print("You cannot use this is as a variable name.") Oif var[0] not in "1234567890": print("This is a good variable name.") else: print("You cannot use this is as a variable name.")
