Machine Learning with Python video 8 :How to split the dataset into Test and Train

In this video i will tell you how you can split your database into two sections that is test and train ,i have also explained what are dependent and independent variable we will be using sklearn's train_test_split package to split our dataset
* train data : it does what the name suggests it trains our machine learning algorithm
* test data : after the model is trained test data is used to test its efficiency

I APPRECIATE YOUR WORK AND ONLY SOME PEOPLE ARE MAKING THIS QUARANTINE PRODUCTIVE AND ARE GRINDING SO SHOUTOUT TO ALL.THANX FOR VIDEOS.

I find the iloc code too restrictive, especially if you adjust the data later in the game. Instead I prefer to use code like:

column_names= df.columns
features = column_names[1:]
label = column_names[0]
display(features, label)

so at any point I can ask/query/return df[label] or df[features] without grid numerical references. This way for future iterations I can add or drop a column and only this section needs to be updated.

dependent = df[label].values
independent = df[features].values

What causes the error found input variables inconsistent with samples [7, 5000]

If i have 1000 rows in dataset. Then how can select first 200 rows for testing and last 800 rows for training instead of select randomly in splitting?
