Ø The if…elif…else Ladder
Let’s PLug-in
State whether the following statements are true or false.
1. A low-level language is a programming language that is machine
dependent. __________
2. Python provides two commonly used functions input() and print() for input
and output. __________
3. Variables are memory reference points where we store values which can be
accessed or changed later. __________
4. Assignment operators are used to compare the value of the two operands
and returns True or False accordingly. __________
There are situations in life where we must make decisions based on the circumstances. For
example, if it rains, we will stay at home, or else we will visit the market. Similar situations arise
in programming as well, where we need to make some decisions and, based on these decisions,
execute a set of commands. Whether the outcome is true or false, we must decide which action to
take and which statement to execute. In this chapter, we will learn about conditional statements
in Python.
CONDITIONAL STATEMENTS
Conditional statements, also known as decision-making or control flow statements, are used
in programming to execute different blocks of code based on certain conditions. The following
conditional statements are available in Python:
if statement if...else statement
Nested if statement if…elif…else ladder
