Python pass statement:

The pass statement in Python acts like a placeholder which means you can use the pass statement if you don’t want to execute any code if a specific condition matches. So, you can simply place a pass where empty code is not permitted, like in loops, function definitions, class definitions, or in if statements.

Syntax :

The signature for the pass statement is as shown below.

Python pass statement Examples:

Example 1: In this example, we will demonstrate the pass statement with the string.

for i in 'Hello': 
   if i == "H":
      pass
      print('Inside pass block')
   else:
      print (i)

Output

Inside pass block
e
l
l
o

Example 2: In this case, we will use pass statement with a function that does nothing.

#Initializing 
def func1():
	pass
	print("Function is called")
func1()

Output

Function is called

Example 3: In this example, We will demonstrate the use of break, continue and pass statements. We will count number of vowels in a string.

#Initializing 
vowel=['a','e','i','o','u']
consonant=['b','c','d','f','g','h','j','k','l','m','n','p','q','r','s','t','v','w','x','y','z']
v=0
# Using break, continue and pass statements
for i in 'python @ programming $ hello ! how #': 
   if i == "$":
        print("Found $ so terminating....")
        break
   elif i in vowel:
        print("Current letter",i, "is vowel")
        v+=1
        continue
   elif i in consonant:
        pass
        print("Inside pass block for ",i)

print("Total number of vowels",v)

Output

Inside pass block for  p
Inside pass block for  y
Inside pass block for  t
Inside pass block for  h
Current letter o is vowel
Inside pass block for  n
Inside pass block for  p
Inside pass block for  r
Current letter o is vowel
Inside pass block for  g
Inside pass block for  r
Current letter a is vowel
Inside pass block for  m
Inside pass block for  m
Current letter i is vowel
Inside pass block for  n
Inside pass block for  g
Found $ so terminating....
Total number of vowels 4
