What is list?
A List is another name for an array.
Lists are one of 4 built-in data types in Python used to store collections of data, the other 3 are Tuple, Set, and Dictionary, all with different qualities and usage.
Example
PayilagamList= ["sneka", "divya", "Santhosh"]
print(PayilagamList)
Output: ['sneka', 'divya', santhosh']Taking Input:
The input function first take the input from the user and converts into a string.
The input function is used in all latest version of the Python. It takes the input from the user and then evaluates the expression.
Example:
payilagam = input(“Best Software Training Institute”)
print(“Best Software Training Institute”+ payilagam)
Input a list in Python:-
Python’s versatility and user-friendly syntax make it an ideal choice for tasks that involve processing lists of elements. This knowledge will help you incorporate user-generated data into your Python programs, enhancing their functionality and interactivity.
Using a combination of input() and list comprehension, you can dynamically design a list containing user-supplied values.
How To Input a List in Python?
In python list by using various methods, it is direct assigning a square brackets.
payilagam_list=[‘avasoft’,’fss’,’qantler’,’mvi technonlogy’]
print(payilagam_list)
O/P: ['avasoft', 'fss', 'qantler', 'mvi technonlogy']
How to take list input in python in single line.
It can be easily done in the Java using the scanner() method. Python provides the two methods that help us to take multiple values or input in one line. In Python single line use input() and split() fucntion. The input() functions accepts a user defined the value example string, chracter, int, float input from the user , and the split() function splits an input string by space.
text = 'Python is PL'
# split the text from space
print(text.split())
# Output: ['Python', 'is', 'PL']
another example:
txt = "welcome to the Payilagam"
x = txt.split()
print(x)The split method is used to getting multiple inputs from the users.
Syntax is input().split(separator, maxsplit)
separator is the delimiter based on which string will be split.
If the separator is not specified, any whitespace (spaces, tabs, newlines) is used as the default split.
Maxsplit this is optional parameter that specifies the maximum numbers of split.
Maxsplit is the maximum of split the strings.
Maximum+1 is returned the elements.
sentence = "Payilagam Software Training Institute."
words = sentence.split(maxsplit=2)print(words) # Output: [‘Payilagam’, ‘Software’, ‘Training Institute.’]
User input to given split function split it on white spaces using split() function.
Example: (use code list)
How to input list in python example:
The sequence is the most fundamental data structure in Python for storing multiple elements all at once. Every elements of a series is given a number that represents its index or locations.
The first elements is called zero, the second elements is called one. That is called Index value in Input list in Python.
My_list Value=[0, 2, 4, 6, 8]
0 value is index of 1, 2 is Index of 1, 4 is index of 3. That is called index value.
How to take list input in Python using for loop:-
In Python input list in following this approach.
# Taking list input using for loop
n = int(input(“Enter the number of elements: “))
my_list = []
print(“Enter the elements, one by one:”)
for i in range(n):
element = input(“Element {}: “.format(i + 1))
my_list.append(element)
print(“The entered list is:”, my_list)
In this example, the code first takes the number of elements (n) as input.
Then, it uses a for loop to iterate n times, prompting the user to enter each element individually. The elements are then appended to the my_list using the append() method.
You can modify the code according to the type of elements you want to input (e.g., integers, floats, strings) and any specific requirements you may have for the input process.
Accept a list of number as an input in Python:
When you create this program in Python, you will need Python’s functions like, list.append() function, input() function, for loop with range() function.
Write a python program to take list as input and create a list from user input:
- First of all, declare a list in python
- Take Input a limit of the list from the user.
- Use for loop to take a single input number from the user.
- Use list.append() to add elements in python list.
- Print the list using for loop.
Python Program to input, append and print the list elements:
# declare a list
myList = []
# take number from user, how many element in list
n = int (input ("How many element in list :- "))
# append element into list using list.append
for i in range (n) :
storeElement = int (input ("Enter an integer num :- "))
myList.append (storeElement)
# print all elements
print("Input list elements are: ")
for i in range (n) :
print(myList [I])Output:
How many element in list :- 7
nter an integer num :- 28
Enter an integer num :- 45
Enter an integer num :- 61
Enter an integer num :- 83
Enter an integer num :- 11
Enter an integer num :- 26
Enter an integer num :- 37
Input list elements are:
28
45
61
83
11
26
37n Simple way Python using Slicing method. Slicing allows to extract the a portion of the list by specifying the start and end indices
Syntax list [start:end]numbers = [72, 8, 6, 75, 76,82, 85, 89, 90]
slicing 1 = numbers[:5] # Slices from the beginning to the 5th element (excluding the 5th element)slicing 2 = numbers[5:]
print(“slicing 1:” slicing 1)
print(“slicing 2:” slicing 2)
Output:
Slicing 1: 76
Slicing 2: 76
The Split split() Method will generate us get multiple inputs from the user and assign them to the respective variables in one line.
number=input(“Enter the NUMBER”)
numbers-list =numbers_list(split()
print(“numbers_list:”, numbers_list)
slicing 1 = numbers[:5] # Slices from the input Forward order
slicing 2 = numbers[:-5] #Slices from input reverse order Output:
Enter the NUMBER
5 4 3 8 7 6 1 2 5 9
numbers_list: 5
