Applying if-else one-liner on lists in Python

Applying if-else one-liner on lists in Python

aaaaaaaaaaaaaaaaaaaaaaaaa

Examples

  1. "python list comprehension if-else one-liner"

    Description: Use a list comprehension to apply an if-else condition to elements of a list.

    Code:

    # Original list numbers = [1, 2, 3, 4, 5] # Apply if-else condition result = [x * 2 if x % 2 == 0 else x - 1 for x in numbers] print(result) # Output: [0, 4, 2, 8, 4]

    Explanation: This one-liner uses a list comprehension to double even numbers and subtract one from odd numbers.

  2. "python conditional expression in list comprehension"

    Description: Implement a conditional expression within a list comprehension.

    Code:

    # Original list words = ['apple', 'banana', 'cherry'] # Apply conditional expression result = [word.upper() if len(word) > 5 else word for word in words] print(result) # Output: ['apple', 'banana', 'CHERRY']

    Explanation: Converts words with more than 5 characters to uppercase using a list comprehension with a conditional expression.

  3. "python apply if-else in list elements"

    Description: Apply an if-else condition to each element in a list and create a new list.

    Code:

    # Original list scores = [85, 45, 76, 90, 62] # Apply if-else condition results = ['Pass' if score >= 50 else 'Fail' for score in scores] print(results) # Output: ['Pass', 'Fail', 'Pass', 'Pass', 'Pass']

    Explanation: Creates a new list indicating 'Pass' or 'Fail' based on whether the score is above or below 50.

  4. "python ternary operator in list comprehension"

    Description: Use the ternary operator to conditionally modify list elements.

    Code:

    # Original list numbers = [10, 20, 30, 40, 50] # Apply ternary operator doubled = [n if n % 2 == 0 else n + 1 for n in numbers] print(doubled) # Output: [10, 20, 30, 40, 51]

    Explanation: Uses the ternary operator to keep even numbers unchanged and increment odd numbers by 1.

  5. "python if-else expression for list transformation"

    Description: Apply an if-else expression to transform elements of a list.

    Code:

    # Original list temperatures = [30, 45, 60, 75, 90] # Apply if-else expression temps_celsius = [(temp - 32) * 5 / 9 if temp > 32 else temp for temp in temperatures] print(temps_celsius) # Output: [30, 45, 60, 75, 32.22222222222222]

    Explanation: Converts Fahrenheit temperatures to Celsius if they are above freezing (32��F), otherwise keeps the temperature unchanged.

  6. "python list comprehension with if-else and function call"

    Description: Use a list comprehension with an if-else statement to call a function conditionally.

    Code:

    # Original list numbers = [3, 5, 7, 9, 12] # Function to apply def process(num): return num ** 2 # Apply if-else condition processed = [process(n) if n % 2 != 0 else n for n in numbers] print(processed) # Output: [9, 25, 49, 81, 12]

    Explanation: Applies the process function to odd numbers and keeps even numbers unchanged using a list comprehension.

  7. "python inline if-else in list processing"

    Description: Use an inline if-else statement to process a list.

    Code:

    # Original list ages = [15, 22, 35, 42, 18] # Apply inline if-else age_groups = ['Minor' if age < 18 else 'Adult' for age in ages] print(age_groups) # Output: ['Minor', 'Adult', 'Adult', 'Adult', 'Minor']

    Explanation: Classifies ages into 'Minor' or 'Adult' based on whether they are below or above 18.

  8. "python using if-else within list comprehension for string modification"

    Description: Modify strings in a list based on a condition using an if-else statement.

    Code:

    # Original list strings = ['hello', 'world', 'foo', 'bar'] # Apply if-else condition modified = [s.upper() if len(s) > 3 else s for s in strings] print(modified) # Output: ['HELLO', 'WORLD', 'foo', 'bar']

    Explanation: Converts strings with more than 3 characters to uppercase while leaving shorter strings unchanged.

  9. "python conditional list generation with if-else"

    Description: Generate a list conditionally using if-else logic.

    Code:

    # Original list numbers = [1, 4, 6, 8, 10] # Generate new list with condition results = [x / 2 if x % 2 == 0 else x * 2 for x in numbers] print(results) # Output: [2, 2.0, 3.0, 4.0, 5.0]

    Explanation: Divides even numbers by 2 and doubles odd numbers using a conditional list comprehension.

  10. "python one-liner to apply if-else on list elements"

    Description: Apply an if-else condition to each element in a list using a one-liner expression.

    Code:

    # Original list values = [5, 8, 12, 18, 21] # One-liner if-else application updated_values = [v - 5 if v > 10 else v + 5 for v in values] print(updated_values) # Output: [10, 13, 7, 13, 16]

    Explanation: Subtracts 5 from values greater than 10 and adds 5 to the rest using a one-liner if-else expression.
