Rewrite the following code fragment that saves on the number of comparisons:

if (a == 0) : 
  print ("Zero")
if (a == 1) : 
  print ("One")
if (a == 2) : 
  print ("Two")
if (a == 3) : 
  print ("Three")

Under what conditions will this code fragment print "water"?

if temp < 32 :    
   print ("ice")  
elif temp < 212:  
   print ("water")
else :            
   print ("steam")

What is the error in following code? Correct the code:

weather = 'raining'       
if weather = 'sunny' :
   print ("wear sunblock")
elif weather = "snow":    
   print ("going skiing") 
else :                    
   print (weather)        

What is the output of the following lines of code?

if int('zero') == 0 :       
   print ("zero")            
elif str(0) == 'zero' :          
   print (0)                  
elif str(0) == '0' :         
   print (str(0))             
else:                         
   print ("none of the above")
