In Python, you can achieve the equivalent of dictionary.get(key, default) for lists by using a simple conditional statement along with the length of the list. Here's a concise way to get the nth element of a list or a default value if the index is out of bounds:
pythonCopy code
my_list = [10, 20, 30, 40, 50]
n = 2 # The index of the desired element
default_value = None # Set your default value here
nth_element = my_list[n] if 0 <= n < len(my_list) else default_value
print(f"The {n+1}th element is: {nth_element}")
This one-liner uses a conditional expression (x if condition else y) to check if the index n is within the valid range for the list. If it is, it retrieves the nth element; otherwise, it returns the default value.
Adjust the n variable and the default_value to suit your specific needs. This approach is concise and readable, making it a convenient way to handle list indexing with default values.
