首先安装：pip install handcalcs
handcalcs github官网：https://github.com/connorferster/handcalcs
示例代码
from handcalcs.decorator import handcalc
@handcalc()
def check(x):
y = x ** 2
return y
if __name__ == '__main__':
result = check(3)
print(result[0])
可以得到如下结果：
\begin{aligned}
y &= \left( x \right) ^{ 2 } = \left( 3 \right) ^{ 2 } &= 9
\end{aligned}
Latex显示的效果（也可以用markdown写成$\begin{.......\end{aligned}$格式）：
y = ( x ) 2 = ( 3 ) 2 = 9 \begin{aligned} y &= \left( x \right) ^{ 2 } = \left( 3 \right) ^{ 2 } &= 9 \end{aligned} y?=(x)2=(3)2?=9?
更多公式使用
from handcalcs.decorator import handcalc
from math import sqrt
@handcalc()
def check(a, b):
y = -b + sqrt(a ** 2) / 3
return y
if __name__ == '__main__':
result = check(3, 4)
print(result[0])
得到结果\begin{aligned} y &= \left( - b \right) + \frac{ \sqrt { \left( a \right) ^{ 2 } } }{ 3 } = \left( - 4 \right) + \frac{ \sqrt { \left( 3 \right) ^{ 2 } } }{ 3 } &= -3.0 \end{aligned}，显示效果：
y = ( ? b ) + ( a ) 2 3 = ( ? 4 ) + ( 3 ) 2 3 = ? 3.0 \begin{aligned} y &= \left( - b \right) + \frac{ \sqrt { \left( a \right) ^{ 2 } } }{ 3 } = \left( - 4 \right) + \frac{ \sqrt { \left( 3 \right) ^{ 2 } } }{ 3 } &= -3.0 \end{aligned} y?=(?b)+3(a)2??=(?4)+3(3)2???=?3.0?
如果只需要公式，可以对latex修改一下：
y = ( ? b ) + ( a ) 2 3 \begin{aligned} y &= \left( - b \right) + \frac{ \sqrt { \left( a \right) ^{ 2 } } }{ 3 } \end{aligned} y?=(?b)+3(a)2???
