What are the three parts of a for loop control? Write a for loop that prints the numbers from 1 to 100.

A `for` loop in programming typically consists of three parts:

1. Initialization: 这里声明并初始化一个计数器变量，它会在每次循环开始前设置到一个新的值。
2. Condition: 检查计数器是否满足某个条件。如果满足，则继续执行循环体；如果不满足，则跳出循环。
3. Increment/Decrement: 循环结束后对计数器变量进行更新，通常是增加或减少其值。

Here's an example of a `for` loop in Python that prints the numbers from 1 to 100:

for i in range(1, 101):
    print(i)

In this code snippet:
- `i` is the counter variable that starts at 1 (`range(1, 101)` generates a sequence of numbers from 1 to 100).
- The condition `i < 101` checks if `i` is less than 101; if true, it will continue printing.
- After each iteration, `i` is incremented by 1 (`i += 1`, implicit in the `range` function).
