py-eval-in-order 0.1.1

A Python package for evaluating multiple boolean conditions (uses eval) IN ORDER.

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

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
