In recreational mathematics, a Harshad number in a given number base, is an integer that is divisible by the sum of its digits when written in that base. Example: The number 18 is a Harshad number in base 10, because the sum of the digits 1 and 8 is 9 (1 + 8 = 9), and 18 ...
Check if the input is a number using int() or float() in Python Theint()orfloat()method is used to convert any input string to a number. We can use this function to check if the user input is a valid number. If the user input is successfully converted to a number usingint()orfl...
A positive integer greater than 1 which has no other factors except 1 and the number itself is called a prime number. 2, 3, 5, 7 etc. are prime numbers as they do not have any other factors. But 6 is not prime (it is composite) since, 2 x 3 = 6. Example 1: Using a flag ...
print(isinstance(value, int))适用场景：需要兼容int子类或继承int的对象。注意事项：浮点数5.0会被判定为False。无法识别字符串形式的整数，例如’2024’。方法三：字符串验证法 原理：将变量转为字符串后检查是否符合整数格式。示例代码：data = ’ -123 ’clean_data = data.strip()if clean_data.lstrip(’...
