我是 python 新手，问题可能听起来很傻，但我想澄清一下。在学习的过程中，我遇到了 python 允许三引号（“””）作为多行注释和字符串文字的代码。那么 python 如何知道它是作为注释还是字符串文字。
"""This
is treated
as comment
and ignored"""
a = """It is
treated as
string literal"""
print(a)
输出：-
It is
treated as
string literal
【问题讨论】：
本质上，如果三引号未分配给变量或文档字符串，python 将忽略它。例如
""""This is a module-level docstring""""
def randomFunction():
"""This will be treated as a docstring,
so if you were to run help(randomFunction) it
will display whatever is in here"""
a = """This is actually assigned to a variable,
and thus python will interpret it as such"""
"""This by itself is just an unassigned string variable """
在两个引号内的字符串也是如此。
【讨论】：
"This by,itself will be ignored" 或['this', 'will', 'be', 'ignored']。三重引号没有什么特别之处，可以忽略不计。如果您不对其进行任何操作，随机表达式将被评估并丢弃。
