String ConcatenationTo concatenate, or combine, two strings you can use the + operator.ExampleGet your own Python Server Merge variable a with variable b into variable c: a = "Hello"b = "World"c = a + b print(c) Try it Yourself » ...
In Python programming, it is a very common task to concatenate multiple strings together to the desired string. For example, if the user’s first and last names are stored as strings in different places. You can create the full name of the user by concatenating the first and last name. I...

print(my_variable) 2.TypeError: unsupported operand type(s) for +: 'int' and 'str' 错误原因: 对不同类型的变量进行不支持的操作,例如将整数和字符串相加。 解决方案: 确保操作数类型兼容,可以使用类型转换函数 (例如 str()、int()、float()) 进行转换。
这里statement1和statement2两个变量都为字符串,但是quantity这个变量为整数,因此print statement1 + quantity + statement2会报错TypeError: cannot concatenate 'str' and 'int' objects, 提示不能将字符串和整数拼接合并。解决的办法是使用str()这个函数将quantity从整数转化为字符串,举例如下: ...
