尝试评估包含赋值的代码块的语法错误

Question

我正在尝试将英文转换为 python 代码，我是这样做的：

english.eng:

the following line is a comment: This is a demo of english programming language
set a new variable dorito as "yum"
if dorito is "yum" then do
  print in the terminal ("dorito is")

main.py:

f = open("english.eng", "r")
pe = f.read()
pe = pe.replace("the following line is a comment:", "#")
pe = pe.replace("as", "=")
pe = pe.replace("set a new variable ", "")
pe = pe.replace(" is ", " == ")
pe = pe.replace(" then do", ":")
pe = pe.replace("print in the terminal ", "print")
print(pe)
eval(pe)

但是随后：出现以下错误：

Traceback (most recent call last):
  File "main.py", line 10, in <module>
    eval(pe)
  File "<string>", line 2
    dorito = "yum"
           ^
SyntaxError: invalid syntax

Answer 1

eval 不适用于赋值操作。也许，您应该在您的案例中使用 exec。
