Python – Break

Python – Break:

In this tutorial, we will learn about the Break statement in Python. Break statement is used to terminate the loop program at a point.

Let us understand the below example which do not have “break” statement will go through multiple iterations till the value of i becomes 109.

Example:

>>> for i in range(100,110):

...     print('Assigned value of i is ',i)

...     for num in range(100,i):

...                             print(i,num)

...

Below is the output:

Assigned value of iis  100

Assigned value of iis  101

101 100

Assigned value of iis  102

102 100

102 101

Assigned value of iis  103

103 100

103 101

103 102

Assigned value of iis  104

104 100

104 101

104 102

104 103

Assigned value of iis  105

105 100

105 101

105 102

105 103

105 104

Assigned value of iis  106

106 100

106 101

106 102

106 103

106 104

106 105

Assigned value of iis  107

107 100

107 101

107 102

107 103

107 104

107 105

107 106

Assigned value of iis  108

108 100

108 101

108 102

108 103

108 104

108 105

108 106

108 107

Assigned value of iis  109

109 100

109 101

109 102

109 103

109 104

109 105

109 106

109 107

109 108

Now, let us break the loop when the value of i becomes 105. Below is the code and output for clarification.

Example

>>> for i in range(100,110):

...     print('Assigned value of i is ',i)

...     for num in range(100,i):

...                             print(i,num)

...     if i==105:

...             break

...

Below is the Output:

Assigned value of iis  100

Assigned value of iis  101

101 100

Assigned value of iis  102

102 100

102 101

Assigned value of iis  103

103 100

103 101

103 102

Assigned value of iis  104

104 100

104 101

104 102

104 103

Assigned value of iis  105

105 100

105 101

105 102

105 103

105 104
