Rana Hasnain KhanFeb 12, 2024PythonPython Lambda Lambdafunctions, also known as anonymous functions, are a concise way to define small, one-line, and throwaway functions without a formal function definition in Python. They offer a compact and efficient approach to solving problems in Python program...
The above lambda function is equivalent to writing this:Python def add_one(x): return x + 1 These functions all take a single argument. You may have noticed that, in the definition of the lambdas, the arguments don’t have parentheses around them. Multi-argument functions (functions that...

Or, use the same function definition to make both functions, in the same program: Example defmyfunc(n): returnlambdaa : a * n mydoubler = myfunc(2) mytripler = myfunc(3) print(mydoubler(11)) print(mytripler(11)) Try it Yourself » ...
