Getting wrong results in Search Cursor Python script?

[المشرف العام]

I have two functions1. First one will crated the feature layer2. second one will access the same created layer and prints the result.

when i run my script first time it will print the wrong results. when i run it second time it will prints correct result...

Wrong Result Script running 1st Time:

getting access to map layer 2

getting access to map layer 2

getting access to map layer 2

getting access to map layer 2

getting access to map layer 2

getting access to map layer 2

getting access to map layer 2

getting access to map layer 2

getting access to map layer 2

getting access to map layer 2

getting access to map layer 2

getting access to map layer 2

getting access to map layer 2

getting access to map layer 3

getting access to map layer 3

getting access to map layer 3

getting access to map layer 3

getting access to map layer 3

getting access to map layer 3

getting access to map layer 3

getting access to map layer 3

getting access to map layer 3

Correct Result: Running script second time1. layer which is creating contains only 5 Rows so my script prints only 5 messages

getting access to map layer 1

getting access to map layer 2

getting access to map layer 3

getting access to map layer 4

getting access to map layer 5
