In this week, I moved on to more basic python concepts and functions

Python Data Types

There are a multitude of data types in python. Some main types are: String, Integer and Float.

In python different data types do different things. And can be assigned using the class like:

print(int(80))

If a data type is not specified, it is assigned by default - which works for most cases.

Logical Conditions (if, elif, else)

If statements compare two variables and validate whether the output is true or false.

The "elif" statement is essentially - else, if.

This means if the previous statement was false, compare this. For example:

if b > a:
     print("b is greater than a")
elif a == b:
     print("a and b are equal")
else:
     print("a is greater than b")

Maya Window Manipulation

In this example I explore the documentation for the window() command and create an if statement.

In this example I have an if statement which deletes the existing window after validating whether it is open or not.

Collections (arrays)

Collections are a way of storing sets of information; improving the efficiency of inputting, outputting and processing data.

Some examples of collection data types are: Dictionaries, Tuples, and Lists.

Loops

Loops allow a section of code to be repeated until a certain condition is met.

A while loop is one type of loop that will repeat until a condition is met.

A for loop will repeat until a certain count is reached.

Week 3 Activities

1)  Making Decisions

number = int(input("Please input a number: "))
if number == 12:
    print("Your number is: "+ str(number))
elif number < 12:
    print("Your number (" + str(number) + ") is lower than 12")
else:
    print("Your number (" + str(number) + ") is greater than 12")

Output:    

2) More Decisions

By changing all the occurances of the number in the code above, I can change the output to a different number e.g. 7.

Output :    

Smallest number Program

num_1 = int(input("Please input a number: "))
num_2 = int(input("Please input another number: "))
numbers = [num_1, num_2]
numbers.sort()
print("The smallest number is: " + str(numbers[0]))

Here I make use of python lists to get the smallest number. This can be done many ways but the advantage of this method is that I can easily add new user inputs to the array and always get the smallest number.

Output:    

3) More Python Conditionals

y = int(input("Enter a number between 1 and 10: "))
if y == 1:
    print("y is 1")
if y > 5:
    print("y is high")
if y < 5:
    print("y is low")
if y != 7:
    print("y is unlucky")
if y == 2 or y == 3:
    print("y is 2 or 3")
if y > 4 and y <= 7:
    print("y is mid-range")

8) Loops

for i in range(6):
    print("Python is awesome!")

9) More Loops

days = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]
weekday = 1
for day in days:
    print(day + " is day " + str(weekday) + " of the week")
    weekday = weekday + 1

Output:   

10) Work Out This!

In this task, I modified the code by adding a condition to the start of the for loop. This checks the number and adds the corresponding suffix (st, nd, rd, etc.). Since all dates after 3rd use the "th" suffix, I could use an else statement as all the numbers with unique  suffixes would be filtered out by the previous conditions.

days = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]
weekday = 1
for day in days:
    if weekday == 1:
        suffix = "st"
    elif weekday == 2:
        suffix = "nd"
    elif weekday == 3:
        suffix = "rd"
    else:
        suffix = "th"
    
    print(day + " is the " + str(weekday) + suffix + " day of the week")
    weekday = weekday + 1

Output
