Print contents of a file ensuring proper error handling?
Assesses fundamental understanding of Python conventions, runtime behavior, and memory/performance considerations.
Hiring managers look for precision, avoidance of ambiguous jargon, and ability to explain trade-offs under real production conditions.
try:
withopen('filename','r')asf:
printf.read()
exceptIOError:
print"Nosuchfileexists"
75 How do we share global variables across modules in Python?
We can create a config file and store the entire global variable to be
shared across modules in it. By simply import ing config, the entire global variable
def ined will be available for use in other modules.
For example I want a, b & c to share between modules.
config.py :
a=0
b=0
c=0
module1.py:
import config
config.a=1
config.b=2
config.c=3
print"a,b&resp.are:",config.a,config.b,config.c
output of module1.py will be

Candidate Response Strategy & Interview Tips
- Start with a concise one-sentence summary: Deliver a direct, confident answer first before expanding into nuances.
- Demonstrate real-world trade-offs: Discuss where this approach excels and when you would avoid it in production systems.
- Discuss complexity & edge cases: Proactively explain time/space complexity or boundary conditions (null values, scale limits).
- Prepare for interviewer follow-ups: Technical hiring panels frequently probe deeper into concurrency, backward compatibility, or alternative libraries.
