CSP-P008: Exception Flow Control in Loop¶

Category: Performance

Severity: LOW

Description¶

Using try/except for common control flow in loops is slow. Prefer checks like in/get/hasattr.

Vulnerable Code Example¶

for key in keys:
    try:
        value = mapping[key]
    except KeyError:
        continue

Safer Code Example¶

for key in keys:
    if key not in mapping:
        continue
    value = mapping[key]
