I Stopped Looping Through Pandas DataFrames. Everything Got Faster
📰 Medium · Data Science
Optimize pandas performance by avoiding loops and using vectorized operations to speed up data manipulation
Action Steps
- Avoid looping through Pandas DataFrames using iterrows() or apply()
- Use vectorized operations like Pandas' built-in functions for data manipulation
- Apply NumPy's universal functions to perform element-wise operations
- Use Pandas' groupby() and merge() functions for data aggregation and joining
- Profile your code using tools like line_profiler to identify performance bottlenecks
