SEE Computer Science | Class 10
CDC New Curriculum – 2083
Topics Covered:
Useful for:ЁЯФе 99% of SEE students lose marks in Python File Handling because they memorize programs instead of understanding the concepts.
Here's the ultimate one-minute revision you should save before your exam. ЁЯУМ
✅ r → Read
✅ w → Write (Overwrite)
✅ a → Append (Add data)
✅ x → Create New File
ЁЯза Memory Trick:
R = Read | W = Wipe | A = Add | X = eXclusive Create
read() → Entire file
readline() → One line
readlines() → All lines (List)
write() → One string
writelines() → Multiple strings
✅ Create a text file
✅ Write data
✅ Append data
✅ Read the entire file
✅ Read the first line
✅ Read all lines
✅ Count characters
✅ Count words
✅ Count lines
✅ Search a word
✅ Copy one file into another

ЁЯФ╣ read() vs readline() vs readlines()
ЁЯФ╣ write() vs writelines()
ЁЯФ╣ w vs a

ЁЯЪА Python CSV Module Mastered! ЁЯУКЁЯРН
The CSV Module is one of the most important topics in SEE Computer Science (Python File Handling). If you can confidently write these programs, you're already ahead of many students. ЁЯТк
✅ Create a CSV file
✅ Write records using writerow()
✅ Read records using csv.reader()
✅ Append new records without deleting old ones
✅ Write multiple records using writerows()
✅ Display specific columns using indexes
✅ Understand file modes (r, w, a, x)
✅ Avoid common exam mistakes like forgetting newline=""
ЁЯУМ Quick Memory Tricks
ЁЯУЭ writer() ➜ Writes data
ЁЯУЦ reader() ➜ Reads data
ЁЯЧС️ w ➜ Wipe & Write
➕ a ➜ Add at the end
ЁЯУД writerow() ➜ One Row
ЁЯУЪ writerows() ➜ Many Rows
ЁЯОп SEE Exam Tip:
Practice writing every program without looking at your notes. In the exam, syntax matters just as much as the logic.
The next stop is ЁЯР╝ Pandas, where filtering and analyzing CSV data becomes much simpler.
ЁЯУЪ Keep practicing. Every program you write today is one less mark you lose tomorrow.
