# Take array of strings
n = int(input("Enter number of strings: "))
arr = []
for i in range(n):
    arr.append(input(f"String {i+1}: "))

# Sort by length
sorted_arr = sorted(arr, key=len)
print(f"Sorted by length: {sorted_arr}")

Output

Enter number of strings: 4
String 1: programming
String 2: hello
String 3: world
String 4: hi
Sorted by length: ['hi', 'hello', 'world', 'programming']

Use sorted() with key=len.

Key Concepts:

  • sorted() sorts list
  • key=len uses length for comparison
  • Returns sorted list
