python实现连接字符串
在Python中连接字符串和变量可以使用“+”运算符或字符串内插(format函数或f字符串)。
例如:
```python
name = "Alice"
age = 25
# 使用“+”运算符连接字符串和变量
greeting = "Hello, " + name + ". You are " + str(age) + " years old."
print(greeting)
# 使用format函数内插变量
greeting = "Hello, {}. You are {} years old.".format(name, age)
print(greeting)
# 使用f字符串内插变量
greeting = f"Hello, {name}. You are {age} years old."
print(greeting)
```
输出:
```
Hello, Alice. You are 25 years old.
Hello, Alice. You are 25 years old.
Hello, Alice. You are 25 years old.
```
注意,如果变量是整数类型,则需要使用str()函数将其转换为字符串类型。f字符串是Python3.6及以上版本才支持的新特性。
