Question

Write a python program to define a tuple to accept 3 food product details such as Products name with their Price and Expiry date in a sub tuple then change the order of price and expiry date in each tuple element

the output should be like this
tuple=(('Cake'(500,'12-09-2020')),('Jelly'(10,'10-09-2020')),('Cream'(256,'12-11-2020'))
tuple=(('Cake'('12-09-2020',500,)),('Jelly'('10-09-2020',10)),('Cream'('12-11-2020',256)))

What I have tried:

t=(('CAKE', (748.0, '07-09-2020')), ('JELLY', (12.0, '07-09-2020')), ('CREAM', (244.0, '03-11-2020')))
for i in range(0,len(t)):
a=t[i][1][0];b=t[i][1][1]
a,b=b,a
print(t)

Try this:

Python

newlist=()
list=(('CAKE', (748.0, '07-09-2020')), ('JELLY', (12.0, '07-09-2020')), ('CREAM', (244.0, '03-11-2020')))
for element in list:
    newitem = (element[0], (element[1][1], element[1][0]))
    newlist = newlist + newitem
print(newlist)

You are welcome. But I recommend that you go to 5. Data Structures — Python 3.7.9 documentation[^] and study the different collection types in Python.
