让我留下了简单的图例以打印适当的符号,第一个必须是正方形,即pch 15,第二个需要为“#”
[平方] y = x ^ 2 [标签] y = 1-x ^ 2
File "/home/username/anaconda3/lib/python3.6/ast.py", line 48, in literal_eval
node_or_string = parse(node_or_string, mode='eval')
File "/home/username/anaconda3/lib/python3.6/ast.py", line 35, in parse
return compile(source, filename, mode, PyCF_ONLY_AST)
File "<unknown>", line 0
^
SyntaxError: unexpected EOF while parsing
现在,正在发生的情况是图例看到1,然后是5,它应该是正方形和井号,我在做什么错了?
