Python: Generate a list and tuple with comma-separated numbers
List and Tuple Generator
Write a Python program that accepts a sequence of comma-separated numbers from the user and generates a list and a tuple of those numbers.
Sample data: 3, 5, 7, 23
Python list:
A list is a container which holds comma separated values (items or elements) between square brackets where items or elements need not all have the same type. In general, we can define a list as an object that contains multiple data items (elements). The contents of a list can be changed during program execution. The size of a list can also change during execution, as elements are added or removed from it.
Python tuple:
A tuple is container which holds a series of comma separated values (items or elements) between parentheses such as an (x, y) co-ordinate. Tuples are like lists, except they are immutable (i.e. you cannot change its content once created) and can hold mix data types.
Sample data : 3, 5, 7, 23
Output :
List : ['3', ' 5', ' 7', ' 23']
Tuple : ('3', ' 5', ' 7', ' 23')
Sample Solution:
Python Code:
# Prompt the user to input a sequence of comma-separated numbers and store it in the 'values' variable
values = input("Input some comma-separated numbers: ")
# Split the 'values' string into a list using commas as separators and store it in the 'list' variable
list = values.split(",")
# Convert the 'list' into a tuple and store it in the 'tuple' variable
tuple = tuple(list)
# Print the list
print('List : ', list)
# Print the tuple
print('Tuple : ', tuple)
Sample Output:
Input some comma seprated numbers : 3,5,7,23 List : ['3', '5', '7', '23'] Tuple : ('3', '5', '7', '23')
Explanation:
The said code prompts the user to input a list of numbers separated by commas. Then it converts the string of numbers into a list and a tuple, and finally it prints both the list and the tuple.
- The first line values = input("Input some comma seprated numbers : ") gets a string of numbers separated by commas from the user using the input() function and assigns it to the variable 'values'.
- The second line splits the string of numbers into a list of individual numbers using the split() method and assigns it to the variable 'list'. This method takes a separator as input, in this case ',' (comma) and returns a list of substrings that were separated by the separator.
- The third line converts the list into a tuple using the tuple() function and assigns it to the variable 'tuple'.
- The fourth line prints the list to the console.
- The fifth line prints the tuple to the console.
Flowchart:
Python Code Editor:
Previous: Write a Python program which accepts the user's first and last name and print them in reverse order with a space between them.
Next: Write a Python program to accept a filename from the user and print the extension of that.
