There are multiple variations of generating pyramids using numbers in Python. Let's look at the 2 simplest formsExamplefor i in range(5): for j in range(i + 1): print(j + 1, end="") print("")OutputThis will give the output1 12 123 1234 12345ExampleYou can also print numbers continuously usingstart = 1 for i in range(5): for j in range(i + 1): print(start, end=" ") start += 1 print("")OutputThis will give the output1 2 3 4 5 6 7 8 9 10 11 12 13 14 15ExampleYou can also print these numbers in reverse usingstart = 15 for i in range(5): for j in range(i + 1): print(start, end=" ") start -= 1 print("")OutputThis will give the output15 14 13 12 11 10 9 8 7 6 5 4 3 2 1
In this article we will be discussing the working, syntax and examples of deque::push_front() function in C++ STL.What is Deque?Deque is the Double Ended Queues that are the sequence containers which provides the functionality of expansion and contraction on both the ends. A queue data structure allow user to insert data only at the END and delete data from the FRONT. Let’s take the analogy of queues at bus stops where the person can be inserted to a queue from the END only and the person standing in the FRONT is the first to be removed whereas in Double ended ...

You can perform arithmetic operations on large numbers in python directly without worrying about speed. Python supports a "bignum" integer type which can work with arbitrarily large numbers. In Python 2.5+, this type is called long and is separate from the int type, but the interpreter will automatically use whichever is more appropriate.As long as you have version 2.5 or better, just perform standard math operations and any number which exceeds the boundaries of 32-bit math will be automatically (and transparently) converted to a bignum.examplea = 182841384165841685416854134135 b = 135481653441354138548413384135 print(a - b)OutputThis will give the output −47359730724487546868440750000

If you want something that converts integers to words like 99 to ninety-nine, you have to use an external package or build one yourself. The pynum2word module is pretty good at this task. You can install it using −$ pip install pynum2wordThen use it in the following way −>>> import num2word >>> num2word.to_card(16) 'sixteen' >>> num2word.to_card(23) 'twenty-three' >>> num2word.to_card(1223)'one thousand, two hundred and twenty-three'If you want to get results like 1.23 million for 1, 230, 000, you can use the humanize library to do so. You can install it using −$ pip install humanizeThen use it in the following way ... Read More
In Java 9, a new method added to the Collectors class: flatMapping(). It is similar to the Collectors.mapping() method in which the flatMapping() method allows us to handle nested collections. The Collectors.flatMapping() method takes a function to be applied to input elements and a collector to accumulate the elements passed through the function. Unlike the Collectors.mapping() method, the Collectors.flatMapping() method deals with a stream of elements that allows us to get rid of unnecessary intermediary collections.Syntaxpublic static Collector flatMapping(Function

A perfect number is a positive integer that is equal to the sum of its proper divisors. The smallest perfect number is 6, which is the sum of 1, 2, and 3.You can find perfect numbers within a given range by testing each number for the given condition in the given range. exampledef print_perfect_nums(start, end): for i in range(start, end + 1): sum1 = 0 for x in range(1, i): # Check if a divisor, if it is, add to sum if(i % x == 0): sum1 = sum1 + x if (sum1 == i): print(i) print_perfect_nums(1, 300)OutputThis will give the output6 28
You can format a floating number to a fixed width in Python using the format function on the string. examplenums = [0.555555555555, 1, 12.0542184, 5589.6654753] for x in nums: print("{:10.4f}".format(x))OutputThis will give the output −0.5556 1.0000 12.0542 5589.6655ExampleUsing the same function, you can also format integers −nums = [5, 20, 500] for x in nums: print("{:d}".format(x))OutputThis will give the output −5 20 500ExampleYou can use it to provide padding as well, by specifying the number before d:nums = [5, 20, 500] for x in nums: print("{:4d}".format(x))OutputThis will give the output −5 20 500The https://pyformat.info/ website is a great ...
