Python pass Statement Example

When the user does not know what code to write, So user simply places pass at that line. Sometimes, pass is used when the user doesn’t want any code to execute. So user can simply place pass where empty code is not allowed, like in loops, function definitions, class definitions, or in if statements. So using pass statement user avoids this error.

Example 1: Pass statement can be used in empty functions

Python3

def function:
  pass

Example 2: pass statement can also be used in empty class

Python3

class geekClass:
  pass

Example 3: pass statement can be used in for loop when user doesn’t know what to code inside the loop

Python3

n = 10
for i in range(n):

  # pass can be used as placeholder
  # when code is to added later
  pass

Example 4: pass statement can be used with conditional statements 

Python3

a = 10
b = 20

if(a<b):
  pass
else:
  print("b<a")

Example 5: lets take another example in which the pass statement get executed when the condition is true 

Python3

li =['a', 'b', 'c', 'd']

for i in li:
    if(i =='a'):
        pass
    else:
        print(i)
