Welcome back, champs! Today marks Day 5 of our 100 Days of Hell with Python Algorithmic Trading journey. In this session, we’ll conclude Python Data Types by covering Tuples, Sets, and Dictionaries before diving into Functions, Classes, and Advanced Topics in the upcoming lessons. Understanding tuples is crucial for working with immutable data structures in algorithmic trading and quantitative analysis.
Let’s get started with today’s lesson and take another step toward mastering algorithmic trading with Python!
Let’s get started what are the tles a tupple in Python is similar to a list the difference between the two is that we cannot change the elements of a tupple once it is assigned whereas we can change the elements of a list in short a tupple is an immutable list this is very important a tle cannot be changed in anyway once it is created it’s same like strings strings are also immutable and tles are also immutable we cannot make any changes once we have created strings and tles whereas in list we can make changes right so that’s the fundamental difference between tles and list now.
Let’s check the characteristics of tles these are ordered same like list lists are also ordered and tles are also ordered so we can say that apart from the immutability all properties of list and tles are similar this is unchangeable of because these are immutable so we cannot make any changes and then it allows duplicate so same like list we can also have duplicate items in tles now let’s quickly jump to the python tles examples so first of all same like list let’s create an empty table so how we can do that let’s say T1 equals to just parenthesis the bracket so when you hit shift enter and print this T1 you will get tle the empty tle right and how you can verify that you can just go and type ID here and you can see that the class is tle correct then let’s create a tle with a single item so similarly what we can do we can write T2 and let’s write tles correct and when you hit print T2 you can see that we have a tles but how do you know that this is tles only it could be a string also right and in fact it is a string how let’s check the type of this and you can see that.
We have a class Str Str so how do we create a tles with a single item for that what we can do instead of this you can just add a comma here and when you print you can see that we have a tle so to resolve that confusion the python has added a comma here so we can differentiate between like a single string or any single integer here so when we add a comma here it will become a tle for the tles with more than one item there is no issue like that and similarly for homogeneous tles same like a list what we can do I just copy and paste it here the first item is a string so so for homogeneous Tes we have to have all the items as single data type right so this also I can have like uh any string we can say like uh let’s say BTC then e and when you print this out you can see that.
We have the tles BTC e right this is homogeneous and similarly for heterogeneous what you can do you can change this value to any other it can be an integer than string then you can change this to a float so float could be 1.5 then Boolean value correct it will become a heterogeneous tles so when you print it out T2 it will be printed out as a heterogeneous tulse correct and again using type conversion this exactly same like we did in list so for example we have a string let’s say BTC correct and when we check the type of this it will be the string right but what you can do you can just convert the type of this so you have you here tle okay and when you check the type you can see that it has converted to tles right so now as you can see that almost all the properties are same accept the immutability because Tes are immutable so.
