The pass statement is a null statement. But the difference between pass and comment is that comment is ignored by the interpreter whereas pass is not ignroed.
The pass statement is generally used as a placeholder i.e. 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 simply places pass there as empty code is not allowed in loops, function definitions, class definitions, or in if statements. So using pass statement user avoids this error.
Syntax:
pass
Example 1: Pass statement can be used in empty functions
Python3
def geekFunction: 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 = 10for 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 = 10b = 20 if(a<b): passelse: 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) |
Output:
b c d
