for i in [1,2,3]

The code will iterate through the list [1, 2, 3], assigning each value to the variable i in turn.
So, on the first iteration, i will be assigned the value 1. On the second iteration, i will be assigned the value 2. On the third and final iteration, i will be assigned the value 3.
The code inside the loop will execute once for each value in the list, using the current value of i in any calculations or operations.

for i in range(1,3)
Sure! The code you provided is a Python for loop that will iterate over the range from 1 to 3 (excluding 3). Here's an example of how it would work:
```python
for i in range(1, 3):
print(i)
```
Output:
```
1
2
```
In this case, the loop will run twice, with `i` taking the values of 1 and 2 in each iteration. The `print()` function is used here to display the value of `i` during each iteration.
for i in range(1,10
for i in range(1,10) 是一个Python中的for循环语句,意思是让变量i从1开始,一直循环到9(不包括10),每次循环都执行其中的代码块。在循环语句中可以使用变量i,例如可以打印出i的值,或者根据i的值执行不同的操作。以下是一个例子:
for i in range(1,10):
print(i)
这段代码会输出从1到9的数字,每个数字占一行。在每次循环中,变量i的值都会自动更新。如果要让i从0开始循环,则可以使用range(10)或者range(0,10)。
