❌ YOU CAN'T USE LAMBDA LIKE THIS IN PYTHON
The main mistake is turning lambda into a logic dump: adding side effects, print calls, long conditions, and calculations to it.
Such lambdas are hard to read, impossible to debug properly, and they violate the very idea of being a short and clean function. Everything complex should be moved into a regular function. Subscribe for more tips every day !
# you can't do this - lambda with state changes
data = [1, 2, 3]
logs = []
# dangerous antipattern
process = lambda x: logs.append(f"processed {x}") or (x * 10)
result = [process(n) for n in data]
print("RESULT:", result)
print("LOGS:", logs)
