PYTHON 3! SIMPLE QUESTION REVIEW. Would like to see if my answers to the questions are correct or are missing anything. Thank you

Q1:Write a function that accepts a string as an argument and displays the string backwards.

My code:

def print_reversed(s):

for letter in reversed(s):

print(letter)

print_reversed(input('Please enter a word: ')) #WOULD LIKE TO PRINT IN A LINE (HORIZONTALLY) INSTEAD OF VERTICALLY

Q2. Explain the difference between "is" and "==". Give an example (different than that used in the chapter 2) that illustrates items that return False for "is" and True for "==".

My answer/code:

"is" will return "TRUE" if two var point to the same object whereas "==" if the objects pointed to by the vars are equal

>>>1000 is 10**3

FALSE

>>>1000 == 10**3

TRUE

Q5. Write nested decision statements(structures) that perform the following: If amount1 is greater than 10 and amount2 is less than 100, display the greater of amount1 and amount2.

My code:

amount1 = input('Enter amount for amount1: ')

amount2 = input('Enter amount for amount2: ')

if (amount1 > 10) and (amount2 < 100):

if amount1 == amount2:

print(amount1, 'equals', amount2)

elif amount1 > amount2:

print(amount1, 'is greater than amount2')

else:

print(amount2, 'is greater than amount1')

else:

print('Amounts not within valid range')

Q1 : changed to print horizontally

CODE:

def print_reversed(s):
for letter in reversed(s):
print(letter, end='') #end is used to change the default setting of printing from vertically to horizontally

print_reversed(input('Please enter a word: '))

OUTPUT:

----------------------------------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------------------------------

Q2: This is working good.

CODE:

print(1000 is 10**3)
print(1000 == 10**3)

OUTPUT:

Q3: Working good.

CODE:

mystring = 'Mon Tue Wed Thur'
space_count = 0
for space in mystring:
if space == " ":
space_count +=1
print(space_count, "spaces")

OUTPUT:

Q4: Working good. Just added print statements to check the output

CODE:

x = 101
if (x > 100):
y = 20
z = 40

print("y = " , y)
print("z = ", z)

OUTPUT:

Q5: Just parsed the input to integer data type, otherwise the code was throwing runtime exception

CODE:

amount1 = int(input("Enter amount for amount1: "))
amount2 = int(input(" Enter amount for amount2: "))
if(amount1 > 10 and amount2 < 100):
   if(amount1 == amount2):
       print(" ",amount1, "equals", amount2)
   elif(amount1 > amount2):
       print(" ",amount1, 'is greater than amount2')
   else:
       print(" ",amount2, 'is greater than amount1')
else:
   print("Amounts not within valid range")
