Question

Given the program
from scitools.StringFunction import
StringFunction
import sys
formula = sys.argv[1]
f = StringFunction(formula)
print f(2)
Will this input work?
Unix/DOS > python function.py ‘t**2’

Answer 1

Yes! It works and results 4 as an output.

Program :

from scitools.StringFunction import  StringFunction

import sys

formula = sys.argv[1]

f = StringFunction(formula)

print f(2)

Output :

4

Explanation :

• As 0th index command line argument will be the program name itself, we will take input 't**2' as 1st command line argument.

• StrinfFunction() is an in-built function that takes a mathematical statement as an input and processes it further.

• On passing the argument to StringFunction() and storing it in variable, we send an argument by variable function thereby, that replaces the unknown variable on the mathematical statement taken as an input and returns the computed value as output.

• So, in the mathematical statement y**2 (y²), y is replaced by the passed value too and gets computed, resulting 4.

• Print it separately, or place the calling function in the print statement itself. That's it.
