## notes made for previous plan to remove null values

check how to remove null values from dataframe

### notes

pandas 

.iloc() - locate by row, col indices

.loc() - locate by row index and col NAME

### how to run python files from terminal

- [python3 main.py](https://realpython.com/run-python-scripts/)

 

### Data Cleaning

### 2.13 Lecture

df.drop('Column name', axis=1)

    - where axies = 0 for rows, 1 for columns

    - drops referenced column from data frame

    - inplace=True argument to ensure column stays dropped.

df.drop(1,axis=0).reset_index()

    - new col with old indices

df.drop(1,axis=0).reset_index(drop=True,inplace=True)

df.copy

### 4.1 Lecture Data Sanity Checks - Part 1

df['columnname'].apply(type).value_counts()

    - this looks at and notes the values by type and then counts them

df['colname'] = df['colname'].replace('missing','inf'],np.nan)

    - replaces our specified strings 'missing' and 'inf' 

    -  with np.nan

df['colname'] = df['colname'].astype(float)

    - convert values to float

Review note: when we substitute np.nan in for strings the resulting data type is (if all the other entries are say float) float.

df.info()

    - rerunning this after data cleaning may result in cleaned columns type changing to, say, float.

Check length of each column 

Columns shorter than max col length means missing values as empty cells

#### Alternative approach - clean while loading:

##### using na_values to tell python which values it should consider as NaN

data_new = pd.read_csv('/content/drive/MyDrive/Python Course/Melbourne_Housing.csv',na_values=['missing','inf'])

- on load, above line automatically converts all missing and inf to nan so, running:

data_new['BuildingArea'].dtype

- gives 

dtype('float64')

as only float (and nan which seems to be treated as whatever the rest of the data types are)

#### Review note

data['BuildingArea'].unique()

- above line run before cleaning gives unique values in column as a numpy array

- so can inspect to find out which strings to remove.
