 import os

files=["photo1.png","photo2.png","photo3.png"]
for i ,f in enumerate(files,start=1):
    new_name=f"image_{i}.png"
    print(f"Renamed{f} {new_name}")

Output:

Renamedphoto1.png image_1.png
Renamedphoto2.png image_2.png
Renamedphoto3.png image_3.png


2. Auto Summarize a CSV File

import pandas as pd
data=pd.DataFrame({
    'Name':['Alice','Bob','Charlie'],
    'Score':[90,85,95],
    'Age':[23,25,22]
})
display(data.describe())

Output:

Score
Age
count
3.0
3.000000
mean

75%
92.5
24.000000
max
95.0
25.000000
3. Remove duplicate Entries

import pandas as pd
df=pd.DataFrame({
    'Name':['Alice','Bob','Alice','David'],
    'Score':[90,85,90,88]
})
df_clean=df.drop_duplicates()
display(df_clean)

Output:

Name
Score
0
Alice
90
1
Bob
85
3
David
88
4. Display Current time and date automatically

from datetime import datetime
now=datetime.now()
print("Current Date & Time:" , now.strftime("%Y-%m-%d %H:%M:%S"))

Output:
Current Date & Time: 2025-11-04 22:25:22

5. Convert text to pdf

from fpdf import FPDF

pdf=FPDF()
pdf.add_page()
pdf.set_font("Arial",size=12)
pdf.cell(200,10,txt="hello from python",ln=True,align='C')
pdf.output("note.pdf")
print("Pdf saved as note.pdf")

Output:
Pdf saved as note.pdf


6. Search for a word in multiple text files

import glob
keyword="Python"
for file in glob.glob("*.txt"):
    with open(file) as f:
        if keyword in f.read():
           print(f"'{keyword}' found in {file}")
    

Output:
'Python' found in daily_log.txt
'Python' found in destination_file.txt


7. Generate a random password

import string,random
chars=string.ascii_letters+string.digits+string.punctuation
password=''.join(random.sample(chars,10))
print("Generated password:",password)

Output:
Generated password: U:{t*k,JzK
