如果你想结束一个 if 语句,可以使用 Python 的关键字 "else"。如果在 if 语句的条件为 False 时执行一段代码,可以使用 else 语句。例如:
```
x = 10
if x > 5:
print("x is greater than 5")
else:
print("x is not greater than 5")
```
这段代码会输出 "x is greater than 5"。如果你想执行多个语句,可以使用一个块来组合这些语句,例如:
```
x = 3
if x > 5:
print("x is greater than 5")
print("This will not be printed")
else:
print("x is not greater than 5")
print("This will be printed")
```
这段代码会输出 "x is not greater than 5" 和 "This will be printed"。
如果你想执行多个条件,可以使用 "elif"(即 "else if")语句。例如:
```
x = 3
if x > 5:
print("x is greater than 5")
elif x > 2:
print("x is greater than 2 but not greater than 5")
else:
print("x is not greater than 5 or 2")
```
这段代码会输出 "x is greater than 2 but not greater than 5"。
希望这些信息能帮到你!
