TypeError occurs while statement 2 is running. Give reason. How can it be corrected?
>>> tuple1 = (5) #statement 1
>>> len(tuple1) #statement 2Advertisements
उत्तर
The ‘statement 1’ is creating a variable, tuple1 which is of ‘int’ data type. The ‘statement 2’ is checking for the length of the variable, but the argument passed is an ‘int’ data type. The 'len()' function can return the length only when the object is a sequence or a collection. This is the reason for the type error.
The error can be corrected by adding one comma after ‘5’ in statement 1, as this will create a tuple and as a tuple is a collection, the 'len()' function will not return an error. The correct statement will be:
>>> tuple1 = (5,)
>>> len(tuple1)APPEARS IN
