What are the main difficulties faced when using Lambda functions?

Main difficulties when using Lambda functions in Python:

• Limited syntax: lambda can contain only one expression, without multi-line blocks or complex logic.
• Lack of name: lambda functions are anonymous, which makes debugging and reading stack traces more difficult.
• Understanding complexity: excessive use of lambdas can make the code less readable, especially for beginners.
• Restrictions in usage with statements: assignment operators or other statements cannot be used inside lambda.

Example of a limitation:

# Cannot write multi-line lambda
# This will cause a SyntaxError
f = lambda x: (
    x + 1
    x * 2
)

# Instead, use a regular function

def f(x):
    return x + 1, x * 2

Therefore, for complex logic, it is better to use regular functions.
