CONCEPTS INVOLVED
What is if…else statement in Python?
Decision making is required when we want to execute a code only if a certain condition is satisfied.
The if…elif…else
statement is used in Python for decision making.
Python if Statement Syntax
if test expression:
statement(s)
Here, the program evaluates the test expression
and will execute statement(s) only if the test expression is True
.
If the test expression is False
, the statement(s) is not executed.
In Python, the body of the if
statement is indicated by the indentation. The body starts with an indentation and the first unindented line marks the end.
Python interprets non-zero values as True
. None
and 0
are interpreted as False
.
Python if…else Statement
Syntax of if…else
if test expression:
Body of if
else:
Body of else
The if..else
statement evaluates test expression
and will execute the body of if
only when the test condition is True
.
If the condition is False
, the body of else
is executed. Indentation is used to separate the blocks.
What is for loop in Python?
The for loop in Python is used to iterate over a sequence (list, tuple, string) or other iterable objects. Iterating over a sequence is called traversal.
Syntax of for Loop
for val in sequence:
Body of for
Here, val
is the variable that takes the value of the item inside the sequence on each iteration.
Loop continues until we reach the last item in the sequence. The body of for loop is separated from the rest of the code using indentation.
The return statement
The return
statement is used to exit a function and go back to the place from where it was called.
Syntax of return
return [expression_list]
This statement can contain an expression that gets evaluated and the value is returned. If there is no expression in the statement or the return
statement itself is not present inside a function, then the function will return the None
object.
Python print()
The print() function prints the given object to the standard output device (screen) or to the text stream file.
