File operation for copying content of one file to another without for loop
# Implementation without for loop
# Copying content of 1.txt file to 2.txt after creation of file
# Please provide the 1.txt file in the current folder as input and
# check after runing the program in the same folder for 2.txt
I=open('1.txt',"r")
O=open('2.txt',"w")
C=I.readlines()
O.writelines(C)
I.close()
O.close()

Exceptional handling for Zero Division Error
# if value of x is given as zero the zero divison error generates and program terminates
x=int(raw_input('Enter the number of students failed:'))
y=100/x
print y
# If x is not defined itself the program not terminated instead it goes to except loop
try:
x=int(raw_input('Enter the number of students failed:'))
y=100/x
print y
except ZeroDivisionError:
x=1
y=100/x
print y
x=int(raw_input('Enter the number of students failed:'))
y=100/x
print y
# If x is not defined itself the program not terminated instead it goes to except loop
try:
x=int(raw_input('Enter the number of students failed:'))
y=100/x
print y
except ZeroDivisionError:

Exceptional handling for Name Error
# If x is not defined itself the program not terminated
try:

except NameError:

print y
try:

except NameError:
