for-loop error : "Output exceeds the size limit." (VSCode)-CodePudding

I was trying to make a for loop to sum the integers from 1 to 100 in Python and wrote the code like this :

for i in range(1, 101) :
    sum_list = []
    sum_list.append(i)
    print(sum(sum_list))

but it didn't print the output I wanted (5050) and the VSCode python interpreter showed the message that output exceeded the size limit.

I want to know what causes this error and what I should do if I want to get the correct output.

CodePudding user response：

You’re not getting the output you expect (5050) because the list needs to be initialized before you begin iterating through integers.

For example:

sum_list = []

for i in range(1, 101):
    sum_list.append(i)

print(sum(sum_list))

As far as the error goes, it seems to be a visual code extension’s config. It’s likely due to you printing out the sum of every iteration. I found a similar question on stackoverflow, perhaps the answer could help you as well. I’d recommend checking your VSCode / extension settings.

CodePudding user response：

I'm not sure why you're getting a size limit exception, those only occur when you want to output some very large data (and i think in a jupyter notebook). but for starters I would move the sum_list creation out of the for loop.

sum_list = []
for i in range(1, 101):
    sum_list.append(i)
    print(sum(sum_list))

This worked for me, but I didn't get your error when i ran your code, so

CodePudding user response：

You were not getting the result because you were initializing the list inside the for loop. You need to initialize in the beginning before starting for loop.

sum_list = []
for i in range(1, 101):
    sum_list.append(i)

print(sum(sum_list))
#5050

2.You can get the result my list comprehension as well.

sum_list=[i for i in range(1,101)]
print(sum(sum_list))
#5050

3.another way:

sum_list=list(range(1,101))
print(sum(sum_list))
#5050

4.Directly sum generator expression:

sum(i for i in range(1,101))
#5050
