Iterative Statements

Jump Statements

• Jump Statements are used to control flow of execution of program.
• These statements an only be used in loops. i.e. in while or for loop.
  1. break
  2. continue

Break Statement

• break statement is used to exit from the iterative statements (loops) such asfor, while.
• Break statement terminates the execution of loop immediately, and then program execution will jump to the next statements.

break

n = int(input("Enter a Number :"))
for i in range(2,n) :
  if n%i==0 :
    break
if i==n-1 :
  print("It is a Prime Number")
else:
  print("It is NOT prime Number")

Enter a Number: 9
It is Not a prime Number
Enter a Number: 17 
It is a prime Number

Continue Statement

• Continue statement is used to continue the loop execution.
• It transfer program control to start of loop to retest condition skipping any statements after continue.

continue

lst=["raja","rani","joker","chor","police","mantri"]
for nm in lst :
  if nm=="chor" :
    continue 
  print(nm , " is Clear ")

raja is Clear
rani is Clear
joker is Clear
police is Clear
mantri is Clear

city="Amravati"
for ch in city :
  if ch=='a' or ch='A' :
    continue
  print(ch)

m
r
v
t
i

pass Statement

• pass statement is used when programmer don’t want to execute statement pass statement is null operation.
• Nothing will happen when pass statement has been executed. We will use the pass statement when we don’t want to execute the code, but want the syntactical expressions.
• In Python programming, pass is a null statement.
• The difference between a comment and pass statement in Python is that, while the interpreter ignores a comment entirely, pass is not ignored. However, nothing happens when pass is executed. It results into no operation (NOP).

pass

lst=["raja","rani","joker","chor","police","mantri"]
for item in lst :
  pass 
print("last item is ", item )

Last item is mantri

for n in range(5,11):
  for i in range(1,n):
    print(i, end=' ')
  print()
