Shouldn't you have to set up the file like PL/SQL?
with declare, begin and end Example here: https://docs.oracle.com/cd/B13789_01/app...06_ora.htm
cx_oracle is supposed to be able to run these queries directly from the file
(looking at docs here): https://oracle.github.io/python-cx_Oracle/

Hi Larz ,
Thanks for explaining it . I know Why this is happening but I am not getting how to remove ' from string .
I will share updated code .

import cx_Oracle
from datetime import datetime


#reading query from file 

f = open('C:/Users/pubhatia/Documents/learning/python/query/test.sql')
#print(f.read())
filer = f.read()
print(filer)

print(repr(filer))
f.close()
#filer3=filer
#source_name ='PWS'
filer=filer.replace("\'","")


#print( repr(filer3 )		
filer2="select * from dual"

if filer==filer2:
 print('same value')
else:
 print ('no same ')

#create connection string
conn_str = u'user/pwd@database'
#setting up connection 
conn = cx_Oracle.connect(conn_str)	
c = conn.cursor()
c.execute(filer2)
start_time = datetime.now()
for row in c:
    print( row)
conn.close()
end_time = datetime.now()
print('Duration: {}'.format(end_time - start_time))


		





	

Output:
"select * from dual"
'"select * from dual"'
no same
('X',)
Duration: 0:00:01.239932

if u will check there is ' quote attach to it that is why when I trying to run it it is giving me error.
I am trying to remove these single quotes but not getting anything.
Please help me with this

Output:
"select * from dual"
'"select * from dual"'

This output clearly shows that you have double quotes around your SQL statement in the file.
Note that single quotes around the second print output is due to the fact that you print repr() of the string, not they are actually there, so it's not possible to remove them (line #16)
I told you file should look like this

Output:
SELECT * FROM dual;

just in case - don't put new line (i.e. don't hit ENTER) at the end of the line, even if it doesn't matter in SQL
