How to fix basic for loop? Python

Question

I am having problems with a for loop. I have a list consensusSize which contains a range of random numbers. I only want to print if the number is greater than 50 and less than 200. Instead it is outputting all of them- want am I doing wrong?

for i in range(0, len(consensusSize)):
... if consensusSize[i]>50 or consensusSize[i]<200:
... print(consensusSize[i])

• Nelewout: It's already in your own writing: I only want to print if the number is greater than 50 and less than 200. Compare this with your conditional.
• mdasari: Use and instead of or

Answer 1

You should think of the python for-loop as a for-each loop:

for i in consensusSize:
 if 50 < i < 200:
 print(i)

This would simplify your solution.

Answer 2

You should use an and:

if consensusSize[i]>50 and consensusSize[i]<200:

• vanilla_2020: but then it prints nothing. There is definitely items in the list that fulfill the rule. e.g. 178,7,63
• 0bero: What is the value of consensusSize? I just tried it on the console and it works.

Answer 3

Use "and" in line 2 instead of "or".

if consensusSize[i]>50 and consensusSize[i]<200:

Answer 4

x_list=[10,20,30]
y_list=[12,10,23]
for x,y in zip(x_list,y_list):
 print(x,y)
