Other than some generic containers like list, Python in its definition can also handle containers with specified data types. Array can be handled in python by module named “array“. They can be useful when we have to manipulate only a specific data type values.
Operations on Array :
1. array(data type, value list) :- This function is used to create an array with data type and value list specified in its arguments. Some of the data types are mentioned in the table below.
|Type Code||C Type||Python Type||Minimum size in Bytes|
|‘q’||signed long long||int||8|
|‘Q’||unsigned long long||int||8|
2. append() :- This function is used to add the value mentioned in its arguments at the end of the array.
3. insert(i,x) :- This function is used to add the value at the position specified in its argument.
The new created array is : 1 2 3 The appended array is : 1 2 3 4 The array after insertion is : 1 2 5 3 4
4. pop() :- This function removes the element at the position mentioned in its argument, and returns it.
5. remove() :- This function is used to remove the first occurrence of the value mentioned in its arguments.
The new created array is : 1 2 3 1 5 The popped element is : 3 The array after popping is : 1 2 1 5 The array after removing is : 2 1 5
6. index() :- This function returns the index of the first occurrence of value mentioned in arguments.
7. reverse() :- This function reverses the array.
The new created array is : 1 2 3 1 2 5 The index of 1st occurrence of 2 is : 1 The array after reversing is : 5 2 1 3 2 1
