Install

To install the package using pip:

pip install single-variable-expression-parser-ALIEZZAT

Usage

Import the module as the following:

from math_expression_parser.single_variable_parser import SingleVariableParser

Then it should be used as:

parser = SingleVariableParser()
parser.set_math_function_text('sqr(16)+1') # For constant expression
result = parser.compute_function_at_value(0) # Here input has no effect on result since it is constant
print(result) # 5 will be printer 

parser = SingleVariableParser()
parser.set_math_function_text('x*2+x^2+5')
result = parser.compute_function_at_value(4) # Value of x will be 4
print(result) # 29 will be printed

Running unit tests

Run python3 -m unittest discover to execute the unit tests via unittest.
