import sys
print(sys.path)  # Verify module search paths

# Solution 3: Relative imports (for packages)
from . import module_in_same_package

# Solution 4: Verify module name spelling
# Correct capitalization and special characters

# Solution 5: Check file naming
# Ensure no local file shadows standard library
