How is break statement different from continue?

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")

What is the output produced by the following code?

x = 1                        
if x > 3 :
   if x > 4 :                
         print ("A", end = ' ')
   else :                    
         print ("B", end = ' ')
elif x < 2:                  
   if (x != 0):
         print ("C", end = ' ')
print ("D")                  

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)
