Array in Python | Set 1 (Introduction and Functions)
Other than some generic containers like lists, Python in its definition can also handle containers with specified data types. The array can be handled in python by a module named “array“. They can be useful when we have to manipulate only 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 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(x) at the ith position specified in its argument.
The newly 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 newly 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 the value mentioned in the arguments.
7. reverse():- This function reverses the array.
The newly 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
