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:
x=1
y=100/x
print y
Exceptional handling for Name Error
# If x is not defined itself the program not terminated
try:
y=50*x
except NameError:
x=1
y=50*x
print y
try:
y=50*x
except NameError:
x=1
y=50*x
print y
Exceptional handling for Key Error
#Without Exceptional handling program terminates if key b not found
s={'d':2,'k':4}
if b in s.keys():
s['b'].append[9]
else:
s['b']= 8
#Exceptional handling for key error and program run without termination
s={'d':2,'k':4}
try:
s['b'].append[9]
except KeyError:
s['b']= 8
s={'d':2,'k':4}
if b in s.keys():
s['b'].append[9]
else:
s['b']= 8
#Exceptional handling for key error and program run without termination
s={'d':2,'k':4}
try:
s['b'].append[9]
except KeyError:
s['b']= 8
