2. Archiving a file using 'with'
• Define a function 'archive' with two parameters, 'zfile' and 'filename'. 'zfile' refers to the *.zip' file to which the file 'filename' is archived.
• Define a function 'writeTo' with two parameters, 'filename' and 'text'. 'text' takes any input string, and 'filename' refers to the name of the file to which the input text is written.
Hint: Use 'zipfile' module and 'with'.
sample.txt python is awesome myarchive.zip
'with' used in 'writeTo' function definition. File : sample.txt is present on system. 'with' used in 'archive' function definition. ZipFile : myarchive.zip is present on system.
import zipfile
import sys
import os
import inspect
# Define 'writeTo' function below, such that
# it writes input_text string to filename.
def writeTo(filename, input_text):
with open(filename, "w") as f:
f.write(input_text)
# Define the function 'archive' below, such that
# it archives 'filename' into the 'zipfile'
def archive(zfile, filename):
with zipfile.ZipFile(zfile, "w") as zip:
zip.write(filename)
if __name__ == "__main__":
try:
filename = str(input())
except:
filename = None
try:
input_text = str(input())
except:
input_text = None
try:
zip_file = str(input())
except:
zip_file = None
res = writeTo(filename, input_text)
if 'with' in inspect.getsource(writeTo):
print("'with' used in 'writeTo' function definition.")
if os.path.exists(filename):
print('File :',filename, 'is present on system.')
res = archive(zip_file, filename)
if 'with' in inspect.getsource(archive):
print("'with' used in 'archive' function definition.")
if os.path.exists(zip_file):
print('ZipFile :',zip_file, 'is present on system.')
'with' used in 'writeTo' function definition.
File : sample.txt is present on system.
'with' used in 'archive' function definition.
ZipFile : myarchive.zip is present on system.
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
