some excercises with lists

For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))

Lists and Tuples example from a Well House Consultants training course
More on Lists and Tuples [link]

This example is described in the following article(s):
• Learning Python - many new example programs - [link]

Source code: yuk Module: Y104

# some excercises with lists

# Set up a list of 4 items
dinner = ["Soup","Chicken","Rice","Water"]

# Change the THIRD one
dinner[2] = "Nan Bread"

# Add two more on the end
dinner += ["Sticky Toffee Pudding","Custard"]

# Insert someting in the 'middle'
dinner.insert(4,"A rest")

print(dinner)

# Most basic loop to handle each member of a list by number
num = 0
while num<len(dinner):
        dinner[num] += " with marmite"
        num += 1

# Use a loop like THIS if you don't care about the position no.
for item in dinner:
        print("I want some",item)

# But if you want to refer to next, or previous ... you need something like this
for posn in range(0,len(dinner),1):
        print("Graham ate all of the ",dinner[posn])

# lists in lists
lunch = [["soup","salad"],["chicken","lamb","rhino"],["Ice Cream"]]
lunch.append(["tea","coke"])
lunch[2].append("Cheese and Celery")

# printing out lists in lists
for course in lunch:
        for option in course:
                print(option," or ",end=" ")
        print()

# Taking the last item off a list ("popping")
dinner = dinner[:-1]

print(dinner)
