The code for item in range(2):
is the start of a loop in Python. Here's what it does:
- It initializes a
for
loop, which will iterate over a sequence of numbers provided by therange(2)
function. - The
range(2)
function generates a sequence of numbers starting from 0 (inclusive) and ending at 2 (exclusive). So, it produces the numbers:[0, 1]
. - The variable
item
will take on each value in the sequence[0, 1]
one at a time during each iteration of the loop.
This means that the code block inside the for
loop (not shown here) will execute twice:
- On the first iteration,
item
will be0
. - On the second iteration,
item
will be1
.
For example, if the loop had a print statement:
for item in range(2):
print(item)
The output would be:
0
1
