I want to transform a C-string to complex expression and simplify it.
For example for the string:
(3+2i)² + 6-i-3+2i
output should be: 8+13i;
260

Python adopted the convention used by electrical engineers. In that field, i is used to represent current and use j as the square root of -1.
In Python, there is a built-in round() function that rounds off a number to the given number of digits. The function round() accepts two numeric arguments, n, and n digits, and then returns the number n after rounding it to n digits.
An complex number is represented by “ x + yi “. Python converts the real numbers x and y into complex using the function complex(x,y). The real part can be accessed using the function real() and imaginary part can be represented by imag().
Parsing is the process of analysing a string of symbols, expressed in natural or computer languages that will accord formal grammar. Expression Parsing in Data Structure means the evaluation of arithmetic and logical expressions.
You need a library that can parse mathematical expressions. Either write your own or take one of the existing ones (like ExprTk).
