Python | Ways to sort list of float values

Given a list of float values, write a Python program to sort the list.

Examples:

Input: list = ['1.2', '.8', '19.8', '2.7', '99.8', '80.7']
Output: ['.8', '1.2', '2.7', '19.8', '80.7', '99.8']

Input: list = [12.8, .178, 1.8, 782.7, 99.8, 8.7]
Output: [0.178, 1.8, 8.7, 12.8, 99.8, 782.7]

Let’s discuss different ways to solve this problem.

# Python code to sort list of decimal values
  
# List initialization
Input =  [12.8, .178, 1.8, 782.7, 99.8, 8.7]
  
# Using sorted and lambda
Output = sorted(Input, key = lambda x:float(x))
  
# Printing output
print(Output)
