为什么在我的终端中打印单引号和代码语法

我在我的教程文件中写了这段代码：

var1 = "hello"
print(var1)
print(type(var1))
var2 = """Peter Piper picked a peck of pickled peppers.
A peck of pickled peppers Peter Piper picked.
If Peter Piper picked a peck of pickled peppers?
Where’s the peck of pickled peppers Peter Piper picked?
"""+"""              The""",var1,""" end"""
print(var2)

但是当我在终端中运行代码时显示如下：

hello
<class 'str'>
('Peter Piper picked a peck of pickled peppers.nnA peck of pickled peppers Peter Piper picked.nnIf Peter Piper picked a peck of pickled peppers?nnWhere’s the peck of pickled peppers Peter Piper picked?n              The', 'hello', ' end')

我想让它打印这个：

hello
<class 'str'>
Peter Piper picked a peck of pickled peppers.
A peck of pickled peppers Peter Piper picked.
If Peter Piper picked a peck of pickled peppers?
Where’s the peck of pickled peppers Peter Piper picked?
The hello end

我不知道该怎么修请帮帮我

我有3.8.6 Python解释器

Answer 1

你可以试试这个

var1 = "hello"
print(var1)
print(type(var1))
var2 = f"""Peter Piper picked a peck of pickled peppers.
A peck of pickled peppers Peter Piper picked.
If Peter Piper picked a peck of pickled peppers?
Where’s the peck of pickled peppers Peter Piper picked?
The {var1} end"""
print(var2)

结果：

hello
<class 'str'>
Peter Piper picked a peck of pickled peppers.
A peck of pickled peppers Peter Piper picked.
If Peter Piper picked a peck of pickled peppers?
Where’s the peck of pickled peppers Peter Piper picked?
The hello end

Answer 2

您已将var2定义为tuple而不是str。要亲自查看，请打印var2:print(type(var2))的类型，您会看到它是一个tuple。

Python允许以三种方式定义tuple：

1. tuple(sequence)
2. (a, b, c)
3. a, b, c

我避免使用第三种语法，因为它很容易在无意中进行编辑。

您需要将var2声明中的,s替换为+s，以便执行级联：

var2 = """Peter Piper picked a peck of pickled peppers.
A peck of pickled peppers Peter Piper picked.
If Peter Piper picked a peck of pickled peppers?
Where’s the peck of pickled peppers Peter Piper picked?
"""+"""              The""" + var1 + """ end"""

Answer 3

使用"操作员，所以只需将最后一行更改为：

"""+"""              The """+var1+""" end"""

使用"意味着您正在创建一个元组。
