The document outlines a Python program that creates a text file named 'sentence.txt' and includes functions to categorize characters into lowercase, uppercase, and digits, as well as to identify palindromes. It specifies the creation of three output files: 'lower.txt', 'upper.txt', and 'digit.txt', along with a file for palindromes named 'palindrome.txt'. The program also includes a display function to print the contents of these files.

PRACTICAL OBJECTIVE & SOLUTIONS


NO.
Write a program in python to create a text file “sentence.txt” and functions
as given below:
7  moveCharacters( ) -to create three files “lower.txt” which contains
all the lowercase letters and “upper.txt” which contains all the
uppercase letters and “digit.txt” which contains all digits from the
above mentioned text file.
 palindrome( ) -to store all palindrome words to a new file
“palindrome.txt”.

Read and display upper.txt, digit.txt and palindrome.txt.

def create():
f=open("sentence.txt","w")
n=int(input("Enter number of lines:"))
for i in range(n):
y=input("Enter line:")
f.write(y+"\n")

f.close()
def moveCharacters( ):
f=open("sentence.txt","r")
#to clear old data
a=open("lower.txt","w")
SOURCE b=open("upper.txt","w")
CODE: c=open("digit.txt","w")
a.close()
b.close()
c.close()

a= open('lower.txt','a')
b= open('uppper.txt','a')
c= open('digit.txt','a')
r= f.readlines()
f.close()

for i in r:
for j in i:
if j.islower():
a.write(j+ ' ')
elif j.isupper():
b.write(j+' ')
elif j.isdigit():
c.write(j+' ')
a.close()
b.close()
c.close()

def palindrome( ):
f = open('sentence.txt','r')
p = open('palindrome.txt','w')
w = f.read().split()
f.close()
#checking if a word is palindrome or not
for i in w:
if i == i[::-1]:
p.write(i+' ')
p.close()

def display():
print()
a= open('lower.txt','r')
b= open('uppper.txt','r')
c= open('digit.txt','r')
p = open('palindrome.txt','r')

print("Letters in lower.txt")
print("- - - - - - - - - - - ")
print(a.read())
print()

print("Letters in upper.txt")
print("- - - - - - - - - - - ")
print(b.read())
print()

print("Letters in digit.txt")
print("- - - - - - - - - - - ")
print(c.read())
print()

print("Letters in palindrome.txt")
print("- - - - - - - - - - - - ")
print(p.read())
print()

a.close()
b.close()
c.close()
p.close()

def main():
