Get first 3 chars of a string.

Write a Python function to get a string made of the first three characters of a specified string. If the length of the string is less than 3, return the original string.

Sample Solution:

Python Code:

# Define a function named first_three that takes one argument, 'str'.
def first_three(str):
    # Check if the length of the input string 'str' is greater than 3.
    if len(str) > 3:
        # If the string is longer than 3 characters, return the first three characters using slicing.
        return str[:3]
    else:
        # If the string is 3 characters or shorter, return the entire string.
        return str

# Call the first_three function with different input strings and print the results.
print(first_three('ipy'))      # Output: 'ipy'
print(first_three('python'))   # Output: 'pyt'
print(first_three('py'))       # Output: 'py'

Sample Output:

ipy                                                                                                           
pyt                                                                                                           
py 

Flowchart:

Python Code Editor:

Previous: Write a Python function to get a string made of 4 copies of the last two characters of a specified string (length must be at least 2).
Next: Write a Python program to get the last part of a string before a specified character.
