1. Writing text to a file using 'with'
• Define a function 'writeTo' with two parameters, 'filename' and 'text'. 'text' takes any input string, and 'filename' refers to the name of the file in which the input text is written.
Hint: Use 'with' to open the file in which the input text is written.
Given Input:
sample.txt
python is awesome
Expected Output:
'with' used in 'writeTo' function definition.
File : sample.txt is present on system.
File Contents are : python is awesome
Program:
#!/bin/python3
import sys
import os
import inspect
# Complete the function below.
def writeTo(filename, input_text):
with open(filename, "w") as f:
f.write(input_text)
if __name__ == "__main__":
try:
filename = str(input())
except:
filename = None
try:
input_text = str(input())
except:
input_text = 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.')
with open(filename) as fp:
content = fp.read()
if content == input_text:
print('File Contents are :', content)
Output:
'with' used in 'writeTo' function definition.
File : sample.txt is present on system.
File Contents are : python is awesome
