Convert sympy tree expression to infix math string

[Anton Makarov]

Hi, there! I use str function to convert sympy tree expression to infix math string. It works fine, except the case when i convert the expression in power, for example:

a = Symbol('a')

res = str(a**2)

print(res)

# a**2

Is there any way to convert sympy tree expression to Standart infix math string form:

a^2 instead of a**2 ?

Thanks...

Why not simply take the math string and use Python to  replace "**" by "^" everywhere? That way you don't have to worry about the fact that "^" is a Python operator. You could also use the reverse replacement to 'reactivate' the string if necessary.
