Python Tip #18 (of 365):
Merge iterables using asterisks: [*first, *second]
To merge iterables, don't do this:
third = list(first) + list(second)
Do this:
third = [*first, *second]
Two reasons I recommend this:
1. It's faster (no need to make 3 new lists instead of 1)
2. "There's a special syntax for that" usually indicates that it's more idiomatic
Remember my recommendation AGAINST using [*old] to copy a list (tip 13)?
"*" isn't for copying so much as merging

Chỉ 5 phút tạo mẫu SaaS nhờ Python + Streamlit + Gemini API. Mỗi khi có ý tưởng, mình viết script Python, dùng Streamlit làm giao diện, gọi Gemini API để thử nhanh. Bạn có cách nào tương tự? #SaaS #Python #Streamlit #GeminiAPI #khởi_nghiệp #tech #đánh_giá

#Python people, which type checker are you you using?
I just tried ty, and was really surprised at how much more output it generates than mypy. There's so much output, I think I prefer what mypy generates.

Henderson & Morris coined "lazy evaluation" in 1976. Almost 50 years later we're still figuring out how to do it without a garbage collector. #golang #rust #python #csharp #dotnet #fsharp https://speakez.tech/blog/seqing-simplicity/

If your #Python #Pandas dataframe has a datetime index, use a slice to retrieve rows in a certain time period:
taxi_df.loc['2025-11-01':'2025-11-03']
But if the rows are unsorted? You get a KeyError.
Solution:
taxi_df.sort_index().loc['2025-11-01':'2025-11-03']

If a text column #Python #Pandas data frame uses lots of memory and repeats, make it a category:
df['x'].memory_usage(deep=True)
# result: 8,093,417
df['x'] = df['x'].astype('category')
df['x'].memory_usage(deep=True)
# result: 154,853
A 99% savings!
