break is a keyword in python just like another programming language and it is used to break the execution of loop statement.

就像另一种编程语言一样， break是python中的关键字，用于中断loop语句的执行。

In the given example, loop is running from 1 to 10 and we are using the break statement if the value of i is 6. Thus when the value of i will be 6, program's execution will come out from the loop.

在给定的示例中，循环从1到10运行，并且如果i的值为6，则使用break语句。因此，当i的值为6时，程序的执行将从循环中执行。

Example 1:

范例1：

for i in range(1,11):
if(i==6):
break
print(i)

Output

输出量

1
2
3
4
5

Example 2: In this example, we are printing character by character of the value/string “Hello world” and terminating (using break), if the character is space.

示例2：在此示例中，如果字符为空格，则按字符/值/字符串“ Hello world”打印字符并终止(使用break)。

for ch in "Hello world":
if ch == " ":
break
print(ch)

Output

输出量
