1. 判断小于 (<)：如果符号左边的值比右边小则返回 True。False2. 判断大于 (>)：如果符号左边的值比右边大则返回 True。True出现上面的错误结果是因为 Python 的浮点运算存在一些 Bug。3. 判断小于等于 (<=)：如果符号左边的值小于或等于右边则返回 True。True4. 大判断于等于 (>=)：如果符号左边的...

TOML 和 Python 之间的直接区别在于 TOML 的布尔值是小写的:true和false。 TOML 字符串通常应使用双引号,并可以用反斜杠(\)转义字符。还可以使用单引号指定字符串。单引号字符串称为文字字符串,其行为类似于 Python 中的原始字符串。最后,还可以使用三引号("""或''')指定字符串。三引号字符串允许您在多行上...

In Python, literals are values that are directly assigned to variables or used in expressions. This includes numeric literals (such as integers and floats), string literals, boolean literals (True and False), and more. For example, if you writex = 5,5is a numeric literal that is being as...
