Split String on Space or Comma

Write a Python program to split a given string (s) into strings if there is a space in s, otherwise split on commas if there is a comma, otherwise return the list of lowercase letters in odd order (order of a = 0, b = 1, etc.).

Input:
a b c d
Split the said string into strings if there is a space in the string, 
otherwise split on commas if there is a comma, 
Output:
['a', 'b', 'c', 'd']

Input:
a,b,c,d
Split the said string into strings if there is a space in the string, 
otherwise split on commas if there is a comma,
Output:
['a', 'b', 'c', 'd']

Input:
abcd
Split the said string into strings if there is a space in the string, 
otherwise split on commas if there is a comma, 
Output:
['b', 'd']

Sample Solution:

Python Code:

# License: https://bit.ly/3oLErEI

# Define a function named 'test' that takes a string 's' as input
def test(s):
    # Check if there is a space in the string 's'
    if " " in s:
        # Split the string into a list of strings using space as the delimiter
        return s.split(" ")
    # Check if there is a comma in the string 's'
    elif "," in s:
        # Split the string into a list of strings using comma as the delimiter
        return s.split(",")
    else:
        # Return a list of lowercase letters with odd ASCII values
        return [c for c in s if c.islower() and ord(c) % 2 == 0]

# Assign a specific string 'strs' to the variable
strs = "a b c d"

# Print the original string 'strs'
print("Original string:")
print(strs)

# Print a message indicating the operation to be performed
print("Split the said string into strings if there is a space in the string, \notherwise split on commas if there is a comma, \notherwise return the list of lowercase letters with odd order:")

# Print the result of the test function applied to the 'strs' string
print(test(strs))

# Assign a different string 'strs' to the variable
strs = "a,b,c,d"

# Print the original string 'strs'
print("\nOriginal string:")
print(strs)

# Print a message indicating the operation to be performed
print("Split the said string into strings if there is a space in the string, \notherwise split on commas if there is a comma, \notherwise return the list of lowercase letters with odd order:")

# Print the result of the test function applied to the updated 'strs' string
print(test(strs))

# Assign another different string 'strs' to the variable
strs = "abcd"

# Print the original string 'strs'
print("\nOriginal string:")
print(strs)

# Print a message indicating the operation to be performed
print("Split the said string into strings if there is a space in the string, \notherwise split on commas if there is a comma, \notherwise return the list of lowercase letters with odd order:")

# Print the result of the test function applied to the updated 'strs' string
print(test(strs))

Sample Output:

Original string:
a b c d
Split the said string into strings if there is a space in the string, 
otherwise split on commas if there is a comma, 
otherwise return the list of lowercase letters with odd order:
['a', 'b', 'c', 'd']

Original string:
a,b,c,d
Split the said string into strings if there is a space in the string, 
otherwise split on commas if there is a comma, 
otherwise return the list of lowercase letters with odd order:
['a', 'b', 'c', 'd']

Original string:
abcd
Split the said string into strings if there is a space in the string, 
otherwise split on commas if there is a comma, 
otherwise return the list of lowercase letters with odd order:
['b', 'd']

For more Practice: Solve these Related Problems:

• Write a Python program that splits a string by spaces if present, else by commas if present, and if neither, returns lowercase letters at odd indices.
• Write a Python program to check for the presence of spaces or commas and split the string accordingly, using conditional logic.
• Write a Python program to process a string and dynamically choose the delimiter based on the input's content.
• Write a Python program to implement a fallback mechanism that returns characters at odd positions if no delimiter is found.
