Python Modulo Operator in Practice How to Check if a Number Is Even or Odd How to Run Code at Specific Intervals in a Loop How to Create Cyclic Iteration How to Convert Units How to Determine if a Number Is a P
Here’s what the syntax of the string modulo operator looks like:Python <format_string> % <values> On the left side of the % operator, <format_string> is a string containing one or more conversion specifiers. The <values> on the right side get inserted into <format_string> in place ...

for i, char in enumerate(text): current_key = key[i % len(key)] 在上面的代码中,可以看到函数第一次使用模运算符: current_key = key[i % len(key)] 此处,该current_key值是根据从 返回的索引确定的i % len(key)。此索引用于从key字符串中选择一个字母,例如Mfrom MODULO。

Let’s look at some examples of using the mod function in Python. Example 1: Python Mod function with positive numbers When both the dividend (the first operand) and the divisor (the second operand) of the modulo operator % are positive, the result is simply the remainder of the division...
