Hi all,

I have a script where I do a loop condition and show ERROR or OK messages depending of each line return. Example:

for v_count_gds in cursor_count:
                    v_count_gd=str(v_count_gds[0])
                    if (v_count_gd != 0):
                        v_cursor_count1 = v_cursor_count1+1
                        print("WRONG!!")
                                                    
                if (v_cursor_count1 < 1) :
                    print("OK ") 

But as it goes line by line, if first check if fine is print "OK" , if second it not fine it print "WRONG", if third line is ok it print "OK"like below:
"OK""
"WRONG"
"OK"


I want to print all WRONG in first lines. How could I do that? add print outputs to a variable and do a kind of sort and at the end print this variable containing all "print" outputs?

Might could use this approach

odd = []
even = []

for i in range(20):
    if i % 2 == 0:
        even.append(str(i))
    else:
        odd.append(str(i))

print(f'Even numbers: {", ".join(even)}')
print(f'Odd numbers: {", ".join(odd)}')

Output:
Even numbers: 0, 2, 4, 6, 8, 10, 12, 14, 16, 18
Odd numbers: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19

That worked almos perfectly. I'm just trying to add a blank line between values, it should be like this ?

print(f'Even numbers: {", ".join(even)}\n') 

it is not working.

f-strings work starting with Python 3.6. Don't use old pythons.

If you want one value per line, maybe something like

odd = []
even = []

for i in range(20):
    if i % 2 == 0:
        even.append(str(i))
    else:
        odd.append(str(i))

print('Even Numbers:')
[print(line) for line in even]
print()
print('Odd Numbers:')
[print(line) for line in odd]

Output:
Even Numbers:
0
2
4
6
8
10
12
14
16
18

Odd Numbers:
1
3
5
7
9
11
13
15
17
19
