这个python代码
import random

k = random.randint(1, 5)
m = random.randint(1, 5)
# Calculate necessary variables
m_k = m - k
m_1 = m - 1
m_plus = m + 1
k_1 = k - 1
k_plus = k + 1

f"\\frac{{(n+{m_plus}) !}}{{{k_plus} ! (n+{m_k}) !}}", # Wrong answer
f"\\frac{{(n+{m}) !}}{{{k_plus} ! (n+{m_k}) !}}" # Wrong answer

该代码生成一个 LaTeX 格式的数学测验,其中包含一个问题和四个多项选择答案,其中一个是正确的。它随机选择 1 到 5 之间的值k
,m
计算派生变量,使用阶乘表达式创建答案,然后对答案进行打乱。最后,它打印 LaTeX 格式的文本以显示问题和答案。
事实上有时我会得到这样的结果:
After simplifying the expression
$$\frac{(n+0) !}{1 ! (n+-1) !} + \frac{(n+0) !}{0! (n+0)!}$$
indicate which of the following results is correct:
\[
\square \; \frac{(n+2) !}{2 ! (n+0) !} \quad\quad \square \; \checkmark \; \frac{(n+1) !}{1 ! (n+0) !} \quad\quad \square \; \frac{(n+1) !}{2 ! (n+0) !} \quad\quad \square \; \frac{(n+0) !}{0 ! (n+0) !}
\]
我不喜欢的是:像 (n+0)! 这样的表达式,我更喜欢 n!;还有 +- 符号,它应该表示符号乘积的减号,但我无法更改。你对此有什么建议吗?
