# py_eio_logic

A simple Python package for evaluating multiple boolean conditions provided as strings.

**WARNING: This package uses `eval()` internally. It is EXTREMELY DANGEROUS to use this package with UNTRUSTED INPUT STRINGS. Malicious input can lead to arbitrary code execution on your system.**
Please ensure all `conditions` passed to `eio()` are from trusted, internal sources only.

## Installation

```bash
pip install py-eval-in-order

from py_eio_logic import eio

# Example 1: Passing individual condition strings
x = 10
y = 5
result = eio("x > 5", "y < 10")
print(f"Result 1: {result}") # Expected: True

result = eio("x == 10", "y == 6")
print(f"Result 2: {result}") # Expected: False

# Example 2: Passing a list of condition strings
z = 7
conditions_list = ["z >= 7", "x + y == 15"]
result = eio(conditions_list)
print(f"Result 3: {result}") # Expected: True

conditions_list_fail = ["z < 5", "x > 0"]
result = eio(conditions_list_fail)
print(f"Result 4: {result}") # Expected: False

# Example 3: When no conditions are passed (evaluates to True)
result = eio()
print(f"Result 5: {result}") # Expected: True


from py_eio import eio

# 'undefined_var' does not exist.
# The second condition would cause a NameError if evaluated.

# Case 1: Error condition is after a False condition
result = eio("1 == 2", "undefined_var > 0")
print(f"Result with error condition after False: {result}")
# Output: Result with error condition after False: False
# (No error message for 'undefined_var' because "1 == 2" is False, and evaluation stops)

# Case 2: Error condition is the first one, or after a True condition
# This will print an error message from the function (due to the try-except block)
# and return None.
result = eio("1 == 1", "another_undefined_var > 0")
print(f"Result with error condition evaluated: {result}")
# Output: Error evaluating condition 'another_undefined_var > 0': name 'another_undefined_var' is not defined
#         Result with error condition evaluated: False
