Here's a concise cheat sheet to help you get started with Python for Data Analytics. This guide covers essential libraries and functions that you'll frequently use.


1. Python Basics
- Variables:
x = 10
y = "Hello"

- Data Types:
  - Integers: x = 10
  - Floats: y = 3.14
  - Strings: name = "Alice"
  - Lists: my_list = [1, 2, 3]
  - Dictionaries: my_dict = {"key": "value"}
  - Tuples: my_tuple = (1, 2, 3)

- Control Structures:
  - if, elif, else statements
  - Loops: 
  
    for i in range(5):
        print(i)
   

  - While loop:
  
    while x < 5:
        print(x)
        x += 1
   

2. Importing Libraries

- NumPy:
  import numpy as np
 

- Pandas:
  import pandas as pd
 

- Matplotlib:
  import matplotlib.pyplot as plt
 

- Seaborn:
  import seaborn as sns
 

3. NumPy for Numerical Data

- Creating Arrays:
  arr = np.array([1, 2, 3, 4])
 

- Array Operations:
  arr.sum()
  arr.mean()
 

- Reshaping Arrays:
  arr.reshape((2, 2))
 

- Indexing and Slicing:
  arr[0:2]  # First two elements
 

4. Pandas for Data Manipulation

- Creating DataFrames:
  df = pd.DataFrame({
      'col1': [1, 2, 3],
      'col2': ['A', 'B', 'C']
  })
 

- Reading Data:
  df = pd.read_csv('file.csv')
 

- Basic Operations:
  df.head()          # First 5 rows
  df.describe()      # Summary statistics
  df.info()          # DataFrame info
 

- Selecting Columns:
  df['col1']
  df[['col1', 'col2']]
 

- Filtering Data:
  df[df['col1'] > 2]
 

- Handling Missing Data:
  df.dropna()        # Drop missing values
  df.fillna(0)       # Replace missing values
 

- GroupBy:
  df.groupby('col2').mean()
 

5. Data Visualization

- Matplotlib:
  plt.plot(df['col1'], df['col2'])
  plt.xlabel('X-axis')
  plt.ylabel('Y-axis')
  plt.noscript('Title')
  plt.show()
 

- Seaborn:
  sns.histplot(df['col1'])
  sns.boxplot(x='col1', y='col2', data=df)
 

6. Common Data Operations

- Merging DataFrames:
  pd.merge(df1, df2, on='key')
 

- Pivot Table:
  df.pivot_table(index='col1', columns='col2', values='col3')
 

- Applying Functions:
  df['col1'].apply(lambda x: x*2)
 

7. Basic Statistics

- Denoscriptive Stats:
  df['col1'].mean()
  df['col1'].median()
  df['col1'].std()
 

- Correlation:
  df.corr()
 

This cheat sheet should give you a solid foundation in Python for data analytics. As you get more comfortable, you can delve deeper into each library's documentation for more advanced features.

If you want to Excel at using the most used database language in the world, learn these powerful SQL features:

Wildcards (%, _) – Flexible pattern matching
Window Functions – ROW_NUMBER(), RANK(), DENSE_RANK(), LEAD(), LAG()
Common Table Expressions (CTEs) – WITH for better readability
Recursive Queries – Handle hierarchical data
STRING Functions – LEFT(), RIGHT(), LEN(), TRIM(), UPPER(), LOWER()
Date Functions – DATEDIFF(), DATEADD(), FORMAT()
Pivot & Unpivot – Transform row data into columns
Aggregate Functions – SUM(), AVG(), COUNT(), MIN(), MAX()
Joins & Self Joins – Master INNER, LEFT, RIGHT, FULL, SELF JOIN
Indexing – Speed up queries with CREATE INDEX
