fprintx is a minimal Python utility for clean, aligned debug printing — especially useful in coding contests or complex loops where output readability matters.
When debugging in competitive programming or trying to inspect multiple values in a loop, messy spacing can make it hard to quickly see what’s happening. You might print values like this:
for i in range(3):
print(i, i * 10, i ** 2)And get:
0 0 0
1 10 1
2 20 4
That’s fine… until the values start getting uneven:
10 100 100
100 1000 10000
That’s where fprintx helps — it aligns and formats each value clearly, so you can visually track changes without squinting.
- Align multiple values (left, center, right)
- Set custom widths for better visual layout
- Apply styles like bold, italic, or underline (optional)
- Optional truncation of long strings
- Return as string if you don’t want to print immediately
from fprintx import printx
for i in range(3):
printx("i:", i, "i*10:", i*10, "i^2:", i**2, widths=[3, 4, 6, 5, 4])Sample output:
i: 0 i*10: 0 i^2: 0
i: 1 i*10: 10 i^2: 1
i: 2 i*10: 20 i^2: 4
To install fprintx directly via pip, simply run:
pip install git+https://github.com/Programming-Sai/fprintx.gitIf you'd like to test, contribute, or run it locally, you can also clone the repository:
git clone https://github.com/Programming-Sai/fprintx.git
