python关于sinx的级数计算程序问题

试图编程一个可以输入x来计算sinx的级数

    term = x, sum = x, eps = 10^(-7)             
    do term = -term*x*x/(2n-1)/(2*n-2);       
    sum = sum + term                           
    while abs(sum) > eps              
end do

运行报错为以下
Input In [7]
do term = -termxx/(2n-1)/(2*n-2); # New wrt old
^
SyntaxError: invalid syntax
不太懂怎么回事

do...while？？？
python不支持这个
