how we can use the python functionalities in the panda series and also you’ll be able to plot any kind of chart like the line chart the bar chart or appy chart you can apply the tail and tail gives the bottom five values right and if you want your custom values you can give here the number whatever you want let’s say if you want the 20 values from the last you can just give 20 and you will get the last 20 values it doesn’t work when we have the index as the integer but if you have a series with the index as the labels as the strings it will work so because we have a series Hello friends welcome back to the day 24 of 100 days of hell with python algo trading.
I hope you like the previous session in which we discussed pandas Theory and then we covered few basic functions and attributes of pandas Series today we’ll continue with that and we will cover some very important and frequently used functions of series we’ll try to cover most of them and then in the next session we will start with again another absolutely important topic that is pandas data frame right so if you just give me few of your minutes then you will be able to understand that how we can use some mathematical functions in Panda series and again how we can use the python functionalities in the panda series and also you’ll be able to plot any kind of chart like the line chart the bar chart or ay chart so without a further.
Let’s get started as as we have already understood the attributes of series okay let’s start some important series methods and which you’ll be going to use frequently so first we have is the head and tell so before that let me just print the series here and let’s check it whether it’s series or not type yeah it’s Series so we are good to go actually the name is DF and generally we keep the name DF of data frame but for now just consider this as a series and actually a series is nothing but a slice of data frame it can be a column or it can be a row so just consider this as a series for now and actually.
It is a series so let’s apply head so head simply means the upper part right so by default it will print out the five values from the top and similarly you can apply the tail and tail gives the bottom five values right and if you want your custom values you can give here the number whatever you want let’s say if you want the 20 values from the last you can just give 20 and you will get the last 20 values and you can even apply the same custom values on the head and you will get the 20 values from the head next method we have is the sample and Sample means let’s say.
We have 100 values and we want a sample so when we apply this sample method it will randomly select any row and it will print out right but if we want a custom value that also we can get so let’s say we have DF and Sample so when we pass without any value we’ll get a single random value and when you again try to print you can see that we are getting always a differ random value right but if you give here let’s say value and five then you will get five different values right and what is the use of this sample let’s say you have a large series and in that the values are sorted so in top we have the smaller values and the last we have the larger values so if you just print the head or tail you will get a biased value right you will not get a clear idea so when you want to have a bird’s eye view of the data what you can do you can simply find a sample values let’s say if the item in your series is like 1,000 then you can get a sample of 100 values and you will get the idea that how the values are there right so means you will not get the buyer value in Sample right so next we have is the value counts the use of value count is it will print the number of times the frequency of any value in in the particular series when we apply DF do value count it will give us this result and we know that most of the prices are not repeating only this one is repeating three times so that’s why we are getting three else all the values are only once right so you can also sort this value as per your need so by default it’s ascending false so you will get the descending value and if you make the ascending is true then you’ll get the value in ascending order right next.
We have is the sort value vales so if I apply sort values then what will happen you know that in this data frame we have two things one is index and second is values so if you apply sort values then these values will be sorted and if you apply the sort index function then these values will be sorted so let’s try this sort values and you’ll see that all the values are sorted and also you can make it ascending is equals to true and you will get the values in ascending order right and when you make this ascending false you will get the values in descending order right similarly you can apply this sort index one more thing that if you apply the in place here in place means the changes or the modifications you make will be permanent right if I make it true then what will happen the values in the file the data frame you have will be changed permanently right so make sure when you’re applying in place you are damn sure right because when you are working in production there will be no chances of mistakes right so you should be aware of that next we have is the sort index and which will sort the index values so let’s apply on this sort index and and you will see that the index has been sorted alphabetically right and if you make ascending false then you will get the values in descending order you can see that we have first the small letter D then alphabetically all the Z to A okay now.
