What does Control Structure Do in a Python

Control the flow of execution in a program.

Control Structures

Control Structures’s benefit is that it enables you to ______________________________ into a single logical unit with one entry point and one exit point.

Control Structures

There are 3 types of Control Structures that we use in Python.

1) Sequence

2) Selection

3) Repetition

Equals: a == b

Not Equals: a != b

Less than: a < b

Less than or equal to: a <= b

Greater than: a > b

Greater than or equal to: a >= b

Yes

Logical Operator

@

If you put ‘and’, you must make sure that all of the conditions is/are correct to make the result True.

If you put ‘or’, you must ensure that at least one condition is/are correct to make the result True.

If you put ‘not’, you must ensure that the condition linked to it is incorrect to make the result True.

If you put ‘not’, you must ensure that the condition linked to it is correct to make the result False.

Selection Control Structure

‘if statement’ is written using the if keyword as the beginning.

when you put an ‘if’, the Python will check the first condition. If the first condition is _____A_____, then Python will read the ‘elif’ keyword. If all previous conditions are ____A______, then Python will read the ‘else’ keyword.

Python will read the conditions until it meets the condition that is correct. After that, it will not read the rest.

Fill A

incorrect

Selection Control Structure

1) One alternative = __________

2) Two alternatives = __________

3) Multiple alternatives = __________
