Python Lambda Functions are anonymous functions meaning that the function is without a name. As we already know that the def keyword is used to define a normal function in Python. Similarly, the lambda keyword is used to define an anonymous function in Python.
Python Lambda Function Syntax:
lambda arguments: expression
- This function can have any number of arguments but only one expression, which is evaluated and returned.
- One is free to use lambda functions wherever function objects are required.
- You need to keep in your knowledge that lambda functions are syntactically restricted to a single expression.
- It has various uses in particular fields of programming besides other types of expressions in functions.
str1 = 'BOARDINFINITY' # lambda returns a function object rev_upper = lambda string: string.upper()[::-1] print(rev_upper(str1))
