The ROUND() function is, obviously, most commonly used when you need to round a number to the nearest integer. For example, if you want to calculate the average of a set of numbers, you might need to round the final value up or down so that it’s an integer. While a computer won...
# Summing up the ASCII values of characters in a string course = "AI" print(sum(ord(char) for char in course)) Output: Explanation: Here, sum() calculates the total ASCII value of all characters in the string. round() Function in Python The round() function rounds off a floating-po...
Q4. In Python, the round() function rounds up or down? The round() function can round the values up and down both depending on the situation. For <0.5, it rounds down, and for >0.5, it rounds up. For =0.5, the round() function rounds the number off to the nearest even number....

map(function, iterable) function是一个函数,它将被应用于可迭代对象中的每个元素。 iterable是一个可迭代对象,如列表、元组等。 map函数的工作原理是将函数function应用于iterable中的每个元素,然后返回一个包含应用结果的新的可迭代对象。新的可迭代对象具有与iterable相同的长度,并且每个元素是将function应用于iterable...
