Simple if is the simplest of all decision making statements. Conditions should be in the form of relational or logical expressions.
Syntax:
if < conditions >
Statements - block 1
 

pass statement is generally used as a placeholder. When we have a loop or function that is to be implemented in the future and not now, we cannot develop such functions or loops with empty body segment because the interpreter would raise an error. So, to avoid this we can use pass statement to construct a body that does nothing.

for word in "Jump Statement":
if word = = "e":
break
print (word, end=")
else:
print ("End of the loop")
print ("\n End of the program")
Output:
Jump Stat
End of the program

range (1,30,1) - will start the range of values from 1 and end at 29
range (2,30,2) - will start the range of values from 2 and end at 28
range (30,3,-3) - will start the range of values from 30 and end at 6
range (20) - will consider this value 20 as the end value(or upper limit) and starts the range count from 0 to 19 (remember always ranget) will work till stop -1 value only)

i= 10 # intializing part of the control variable
while (i<=15): # test condition
print (i, end='\t') # statements - block 1
i=i+1 # Updation of the control variable
else:
print ("\n Value of i when the loop exit",i)
Output:1
10 11 12 13 14 15
Value of i when the loop exit 16

for var in sequence:
# code inside for loop
if condition:

while test expression:
#code inside while loop
if condition:

Program:
ch=input ("Enter a character :")
# to check if the letter is vowel
if ch in ('a', 'A', 'e', 'E', 'i', 'I', 'o', 'O', 'u', 'U'):
print (ch,' is a vowel')
# to check if the letter typed is not 'a' or 'b' or 'c'
if ch not in ('a', 'b', 'c'):
print (ch,' the letter is not a/b/c')
Output 1:
Enter a character: e
e is a vowel
Output 2:
Enter a character :x
x the letter is not a/b/c

Example: Program to illustrate the use of while loop - to print all numbers from 10 to 15
i=10 # intializing part of the control variable
while (i<=15): # test condition
print (i, end='\t') # statements - block 1
i=i+1 # Updation of the control variable
Output:
10 11 12 13 14 15

Simple if statement: Simple if is the simplest of all decision making statements. Condition should be in the form of relational or logical expression.
Syntax:
if :
statements-block1
In the above syntax if the condition is true statements - block 1 will be executed.
Example: Program to check the age and print whether eligible for voting
x=int (input("Enter your age :"))
if x > = 18:
print ("You are eligible for voting")
Output 1:
Enter your age: 34
You are eligible for voting
Output 2:
Enter your age: 16

Python provides the following types of alternative or branching statements:
(i) Simple if statement
(ii) if..else statement
(iii) if..elif statement

A sequential statement is composed of a sequence of statements which are executed one after another. A code to print your name, address and phone number is an example of sequential statement
Example:
# Program to print your name and address - example for sequential statement
print ("Hello! This is Shyam")
print ("43, Second Lane, North Car Street, TN")
Output:
Hello! This is Shyam
43, Second Lane, North Car Street, TN
