The sequence of triangle numbers is generated by adding the natural numbers.
So the 7th triangle number would be 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28.
The first ten terms would be:
1, 3, 6, 10, 15, 21, 28, 36, 45, 55, ...
Let us list the factors of the first seven triangle numbers:

The following iterative sequence is defined for the set of positive integers:

Custom functions to clean data
You'll now practice writing functions to clean data.
The tips dataset has been pre-loaded into a DataFrame called tips. It has a 'sex'
column that contains the values 'Male' or 'Female'. Your job is to write a function
that will recode 'Male' to 1, 'Female' to 0, and return np.nan... |

Many-to-many data merge
The final merging scenario occurs when both DataFrames do not have unique keys for a
merge. What happens here is that for each duplicated key, every pairwise combination
will be created.
Two example DataFrames that share common key values have been pre-loaded: df1 and
df2. Another DataFr... |

Converting data types
In this exercise, you'll see how ensuring all categorical variables in a DataFrame
are of type category reduces memory usage.
The tips dataset has been loaded into a DataFrame called tips. This data contains
information about how much a customer tipped, whether the customer was male or

The power of SQL lies in relationships between tables: INNER JOIN
Here, you'll perform your first INNER JOIN! You'll be working with your favourite
SQLite database, Chinook.sqlite. For each record in the Album table, you'll extract
the Title along with the Name of the Artist. The latter will come from the Artist... |

Loading and exploring a JSON
Now that you know what a JSON is, you'll load one into your Python environment and
explore it yourself. Here, you'll load the JSON 'a_movie.json' into the variable
json_data, which will be a dictionary. You'll then explore the JSON contents by
printing the key-value pairs of json_da... |
