Your task is to implement a function replace_once(t, d), that takes a text t and a replacement dictionary d, and returns the result of replacing words according to the dictionary: if a word appears as a key, replace it with the dictionary value, and if a word does not appear in the dictionary, leave it alone. Given a list of words, you can concatenate them together with spaces in between as follows:
word_list = "I love eating bananas".split()
print("Word list:", word_list)
back_together = " ".join(word_list)
print("Back together:", back_together)
# You can also join them in other ways, btw. Just DON'T do it for this homework.
print("You can also put commas:", ", ".join(word_list))

If the polar bear were taken out of the food chain what would happen to the seal population the seal population would diminish the seal population would grow dramatically the seal population would stay the same the seal population would decrease slightly

What is used to analyze and summarize your data without graphical support

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
