In order to fix a variable you can just set lower and upper bound of that variable to the fix value:

with cplex.Cplex() as cpx:
    x = cpx.variables.add(lb = [0, 0], ub = [1, 1])
    cpx.variables.set_lower_bounds(x[0], 0.5)
    cpx.variables.set_upper_bounds(x[0], 0.5)
    # The variable x[0] is now fixed to 0.5
