How to convert image to pdf in Python
# Python3 program to convert image to pfd
# using img2pdf library
# importing necessary libraries
import img2pdf
from PIL import Image
import os
# storing image path
img_path = "Input.png"
# storing pdf path
pdf_path = "file_pdf.pdf"
# opening image
image = Image.open(img_path)
# converting into chunks using img2pdf
pdf_bytes = img2pdf.convert(image.filename)
# opening or creating pdf file
file = open(pdf_path, "wb")
# writing pdf files with chunks
file.write(pdf_bytes)
# closing image file
image.close()
# closing pdf file
file.close()
# output
print("Successfully made pdf file")
pip3 install pillow && pip3 install img2pdf

If I wanted to get my opportunity to interview at Google or Amazon for SDE roles in the next 6-8 monthsβ¦
Hereβs exactly how Iβd approach it (Iβve taught this to 100s of students and followed it myself to land interviews at 3+ FAANGs):
βΊ Step 1: Learn to Code (from scratch, even if youβre from non-CS background)
I helped my sister go from zero coding knowledge (she studied Biology and Electrical Engineering) to landing a job at Microsoft.
We started with:
- A simple programming language (C++, Java, Python β pick one)
- FreeCodeCamp on YouTube for beginner-friendly lectures
- Key rule: Donβt just watch. Code along with the video line by line.
Time required: 30β40 days to get good with loops, conditions, syntax.
βΊ Step 2: Start with DSA before jumping to development
Why?
- 90% of tech interviews in top companies focus on Data Structures & Algorithms
- Youβll need time to master it, so start early.
Start with:
- Arrays β Linked List β Stacks β Queues
- You can follow the DSA videos on my channel.
- Practice while learning is a must.
βΊ Step 3: Follow a smart topic order
Once youβre done with basics, follow this path:
1. Searching & Sorting
2. Recursion & Backtracking
3. Greedy
4. Sliding Window & Two Pointers
5. Trees & Graphs
6. Dynamic Programming
7. Tries, Heaps, and Union Find
Make revision notes as you go β note down how you solved each question, what tricks worked, and how you optimized it.
βΊ Step 4: Start giving contests (donβt wait till youβre βreadyβ)
Most students wait to βfinish DSAβ before attempting contests.
Thatβs a huge mistake.
Contests teach you:
- Time management under pressure
- Handling edge cases
- Thinking fast
Platforms: LeetCode Weekly/ Biweekly, Codeforces, AtCoder, etc.
And after every contest, do upsolving β solve the questions you couldnβt during the contest.
βΊ Step 5: Revise smart
Create a βRevision Sheetβ with 100 key problems youβve solved and want to reattempt.
Every 2-3 weeks, pick problems randomly and solve again without seeing solutions.
This trains your recall + improves your clarity.
