You can use loan to access the first element, loan to access the second element and so on. Hint: If your for loop is defined as: for loan in loans : You need to build a for loop from scratch and print each loan's information in a separate line in this format - "'Name's took a loan of X. Results: 10 principal outstanding on a loan of 25Ĭonsider our loan example, but this time as a list with each item of the list containing three pieces of information: the borrower's name, the original loan amount, and the principal outstanding. Print (str(y) + " principal outstanding on a loan of " + str(x)) To do so, we can use multiple assignments as shown below: for (x, y) in loan_summary: Suppose we want to print the results in this manner - "Y principal outstanding on a loan of X". Consider an array which contains original loan amounts and the balance principal outstanding on 5 different stocks. This will print each element separately as shown below: 1.0 However, if you wanted to iterate over each separate element of the multi-dimensional array, you can do so using the nditer() method as shown below: Consider the following array: a = np.array(, Loop over Numpy Arrays (Multi-dimensional)įor multidimensional arrays, iteration proceeds over the first axis such that each loop returns a subsection of the array. We can iterate over the elements as follows: import numpy as np Consider the following Numpy array: prices = np.array() If we have a one-dimensional Numpy array, looping over it is easy. Results: The stock GOOGL has a price of 849 Print("The stock " + key + " has a price of " + str(value)) We can iterate over it and print each stock's information on a different line as follows (using for loop). portfolio = Īs you can see, the dictionary contains key-value pairs of stock symbols and their prices. Let's say we have the following dictionary containing the a list of stocks along with their prices. To loop over a dictionary elements, we use the items() method provided with a dictionary object. In this lesson, we will learn about how to loop over python dictionaries and Numpy arrays. In the previous lessons, we learned about how to loop over lists.
