Lambdas Functions

''' EXERCISE #1 Rewrite the following function as a lambda def string_in(substring, original_str): return substring in original_str print(string_in("super","supervisor")) ''' string_in = lambda substring, original_str: substring in original_str print(string_in('super', 'supervisor'))

''' EXERCISE #2 Rewrite the following function as a lambda It calculates the simple interest on an amount def interest(amount, rate): return rate * amount print('The interest returned is ' + "${:,.2f}".format(interest(125000,.085))) ''' interest = lambda amount, rate: rate * amount print('The interest returned is ' + '${:,.2f}'.format(interest(125000, .085)))

# EXERCISE 3 # code your solution for the email builder here firstNames = ['Sofia', 'Juan', 'Aria', 'Mohammed', 'Anna', 'Hiroshi', 'Evelyn', 'Lucas', 'Emma', 'Sebastian', 'Lila', 'Elias', 'Yuna', 'Nathan', 'Sophie', 'Nikolai', 'Jasmine', 'Milo', 'Eva', 'Rohan', 'Alessia', 'Max', 'Leila', 'Adam', 'Maya'] emails = [] lambda_func = lambda names: names.lower() firstNames_lc = map(lambda_func, firstNames) for n in firstNames_lc: new_n = n + '@gatordata.com' emails.append(new_n) for i in emails: print(i)

''' EXERCISE #4 Using the email list that you created, use the filter function to filter out all email addresses that have the letter "n" in them. ''' list(filter(lambda e: 'n' not in e, emails))
