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.

Method #1 :Using lambda

# 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)

Output:

[0.178, 1.8, 8.7, 12.8, 99.8, 782.7]

Method #2 : Using sorted

# Python code to sort list of decimal values

# List initialization
Input =  [12.8, .178, 1.8, 782.7, 99.8, 8.7]

# Using sorted + key
Output = sorted(Input, key = float)

# Printing output
print(Output)

Output:

[0.178, 1.8, 8.7, 12.8, 99.8, 782.7]

Method #3 : Using sort

# Python code to sort list of decimal values

# List initialization
Input =  [12.8, .178, 1.8, 782.7, 99.8, 8.7]

# Using sort + key
Input.sort(key = float)

# Printing output
print(Input)

Output:

[0.178, 1.8, 8.7, 12.8, 99.8, 782.7]
