Help to identify the problem in the Python code

Question

I am Shivashankar and I tried a small python program.

I created two set of programs where both are same. However for the 1st program when I type "quit" it does not break the loop runs infinite loop.
But for the 2nd set the code breaks the loop - works perfect.

What is the problem in 1st program? Why is it running infinite loop?

I pasted two program down below. Please help me.

############## FIRST PROGRAM - does not quit & runs infinite loop
while True:
x=input("> ")
if x.lower()=="help":
print("start - To start the car")
print("stop - To stop the car")
print("quit - To quit the program")
elif x.lower()=="start":
print("car started - Ready to go!!")
elif x.lower()=="stop":
print("car stopped - You can disembark!")
elif x.lower=="quit":
break
else:
print("Hey! I don't understand that.")

############# SECOND PROGRAM - works well when "quit"
while True:
x=input("> ")
if x.lower()=="help":
print("start - To start the car")
print("stop - To stop the car")
print("quit - To quit the program")
elif x.lower()=="start":
print("car started - Ready to go!!")
elif x.lower()=="stop":
print("car stopped - You can disembark!")
elif x.lower()=="quit":
break
else:
print("Hey! I don't understand that.")

Answer 1

In the first code, you dont have paranthesis() after x.lower in the “quit” else if statement:

elif x.lower()==“quit”:
