This function takes a string as input and returns its reverse using slicing ([::-1]). Example: Python 1 2 3 4 5 6 7 8 # Function to reverse a string def reverse_string(s): return s[::-1] print(reverse_string("intellipaat")) Output: Explanation: Here, [::-1] returns the ...
Import a Python module to time specific sections of code. Note: a common module is the datetime module. Obtain the time before a function and again immediately after the function to calculate the execution time. Repeat this with each function to determine which function is taking the longest to...
Here in this example, the cube is a variable that is assigned to a lambda function that takes x as an argument and returns the cube of x. This is why lambda functions are an excellent choice for one-time tasks in your code. Key Features of Python Lambda Functions Here are some of the...
max_wait_time: Provided on creation of a receiver or when calling receive_messages(), the time after which receiving messages will halt after no traffic. This applies both to the imperative receive_messages() function as well as the length a generator-style receive will run for before exiting...

Practical use cases for decorators include logging, enforcing access control, caching results, and measuring execution time. Custom decorators are written by defining a function that takes another function as an argument, defines a nested wrapper function, and returns the wrapper. Multiple decorators ...

When id was called, Python created a WTF class object and passed it to the id function. The id function takes its id (its memory location), and throws away the object. The object is destroyed. When we do this twice in succession, Python allocates the same memory location to this ...
