Quick Start

Three Core Application Scenarios

1. Data Processing

# Handling student scores

scores = [85, 92, 78, 96, 88, 76, 94, 82]

# Basic statistics

average = sum(scores) / len(scores)

print(f”Average score: {average:.1f}”) # 86.4

# Data filtering

high_scores = [score for score in scores if score >= 90]

print(f”Excellent scores: {high_scores}”) # [92, 96, 94]

2. Text Processing

# Handling user feedback

feedback = ” This product is really great! Powerful features and beautiful interface. “

# Text cleaning and analysis

clean_text = feedback.strip()

has_positive = “great” in clean_text

print(f”Positive feedback: {has_positive}”) # True

3. Automating Tasks

# Batch renaming files

files = [“Report_2024_01_15.docx”, “Data_2024_01_16.xlsx”]

for file in files:

name_part, extension = file.split(‘.’)

new_name = f”Project_{name_part.split(‘_’)[1]}_{name_part.split(‘_’)[2]}.{extension}”

print(f”Renaming: {file} → {new_name}”)
