Hello, it's a question count the number of n.

Question

A=list(map(int,input().split()))
n=10
for i in A:
if i>=n:
count+=1
print(count)

As you can see I'm able to count the number n in the list but whenever i give input which is less than it want to print (0) but I'm unable to do that can anyone tell me how can i do that.

Input: 1 1 1 1
Output : No

Answer 1

Akash Gupta ,

additionally to the comment from Jayakrishna🇮🇳 :

- the variable 'count' has to be declared and initialized before it is used
- the final print() statement has to be without any indentation

in general, the task description is missing a bit what you really wanted to count.

- do i understand it correctly that you are expecting n input values as numbers separated by a space?
- and you are then counting only numbers that are greater or equal than 10?

may be you can update your task description.

Answer 2

Akash Gupta ,

here is your code slightly modified.

t=int(input())
count=0
for i in range(t):
n=10
inp = int(input())
if inp>=n:
count+=1
print(f'number of values greater than {n}: {count}')

Lothar
His original code, taking first input as how many lines of input and using split then for each line of input.

Ex: input
2
23 12 7 22
1 1 1 1

So i added t input and loop.
imput data are space separated, t times

(see in linked code).

Answer 4

Akash Gupta
Your input / output explanations are 2 versions. Which one you actually trying? What is the task? You can add link here or copy paste here..

I modified code for the code you added by link as you said it update code..

Is you need modification for original you added in question description?
@Lother given the modified version for that.

If anything not work then add clear details by copy-pasting question and expected input/output details..
Hope you understand..

Answer 5

It asking sign in... Can you share output screen shot..!

Try this:

A=input().split()
count = 0
for i in A:
i =int(i)
if 1<= i <= 100 and i >= 10: count+=1

print(count)

Answer 6

Identation matters in python. Pls save code and share link here..

edit: Akash Gupta

1>=10 false so no output. in all cases since print is inside if block..

Answer 7

Jayakrishna🇮🇳 it happens because of copy wait i will send the code again

Prince Kumar Lothar Jayakrishna🇮🇳https://code.sololearn.com/cDwm64jdKAx6/?ref=app

input -23 54 12 5
Output:3
Input: 1 1 1 1 1
Output:0

Answer 9

Jayakrishna🇮🇳 compiler giving this error NZEC .

Answer 10

Prince Kumar 3 number are greater than 10 that's why

Answer 11

NREC => ? Is this full error description?

You can use filter :

t=int(input())
for i in range(t):
A = filter(lambda x:x>10, map(int, input().split() ))
print(len(list(A)))

Answer 12

Jayakrishna🇮🇳 ,

for your attempt we don't need to use a range for the input, since the input in the filter will be split and then mapped and processed by the lambda:

#t=int(input())
#for i in range(t):
A = filter(lambda x:x>10, map(int, input().split() ))
print(len(list(A)))

Answer 13

A=list(map(int,input().split()))
count = 0
for i in A:
if i>=10:
count+=1

print(count)

#or

A=filter(lambda x : x>=10 and x<=100 , map(int,input().split()))
print(len(list(A)))

#try these two variations

Answer 14

Akash Gupta
Input:

2
-23 54 12 5
1 1 1 1 1

Getting Output:

2
0

What is your expected output?

"able to count number of n in list" - What do you mean by this ? Explanation not matching with code!!
Can you clarify it..?

Answer 15

Akash Gupta No. Am not getting any error.
I posted above test cases and output.
I taken -23 so. If it is +23 then output is 3
What is your expected output?

Answer 16

Jayakrishna🇮🇳 bro you can tell me any different approach for that this code is executed correctly on online compiler but when i submitted on coding contest compiler it giving me error of NREC it's a logical error in my code.

Answer 17

Jayakrishna🇮🇳 tell me another way to count the n in given list.

Answer 18

Jayakrishna🇮🇳
Same error by implementing your code.
Run time error
NZEC
Error
Traceback (most recent call last):
File "./prog.py", line 2, in <module>
ValueError: invalid literal for int() with base 10: '12 15 8 10'
