Introduction to Python
Python is a versatile programming language that is widely used in data science. In this section, you will learn the basics of Python syntax, variables, and data types.
# Hello, World!
print("Hello, World!")
Data Manipulation and Analysis
Data manipulation is a crucial skill in data science. This section covers libraries like Pandas, which allow you to easily manipulate and analyze data.
import pandas as pd
# Load data
data = pd.read_csv("data.csv")
# Data analysis
analysis = data.describe()
Data Visualization
Data visualization is key to understanding your data. In this section, we will explore libraries like Matplotlib and Seaborn to create informative visualizations.
import matplotlib.pyplot as plt
# Plotting
plt.figure(figsize=(10, 6))
plt.plot(data['column_name'])
plt.title('Title')
plt.xlabel('X-axis')
plt.ylabel('Y-axis')
plt.show()
Machine Learning
Machine learning is a powerful tool for data science. In this section, we will cover popular algorithms and techniques, including linear regression, decision trees, and neural networks.
from sklearn.linear_model import LinearRegression
# Linear regression
model = LinearRegression()
model.fit(data[['X']], data['Y'])
Advanced Topics
The advanced topics section will delve into more complex concepts, such as natural language processing, time series analysis, and distributed computing.
Natural Language Processing
Natural language processing (NLP) is the field of data science that focuses on the interaction between computers and human language. In this section, we will explore libraries like NLTK and spaCy.
import nltk
# Tokenization
text = "This is a sample text."
tokens = nltk.word_tokenize(text)
Time Series Analysis
Time series analysis is the study of data points collected over time. In this section, we will cover libraries like Statsmodels and Pandas to analyze time series data.
import pandas as pd
# Time series analysis
data = pd.read_csv("time_series.csv")
model = statsmodels.tsa.arima_model.Arima(data['value'], order=(5, 1, 0))
model_fit = model.fit(disp=0)
Distributed Computing
Distributed computing is the process of breaking a large problem into smaller pieces and solving them across multiple machines. In this section, we will explore libraries like Dask and Spark.
import dask.dataframe as dd
# Distributed computing
data = dd.read_csv("data.csv")
result = data.sum().compute()
