NEW SERVER - 11.9.2020 ... Retiring, March 2020 - sorry, you have missed our final public course.
The Coronavirus situation has lead us to suspend public training - which was on the cards anyway, with no plans to resume

Please ask about private 'maintenance' training for Python, Tcl, Perl, PHP, Lua, etc
Happily continuing private consultancy / programming work
 
some excercises with lists
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)
