The output of the code will be an error because there is a syntax error in the last line. Instead of "a+b", it should be "x+y" to concatenate each element from list a with each element from list b.
The corrected code is:
a=['詹','肖','王']
b=['不败','劳模','废材','可以']
c=[]
for x in a:
for y in b:
c.append(x+y)
print(c)
The output will be:
['詹不败', '詹劳模', '詹废材', '詹可以', '肖不败', '肖劳模', '肖废材', '肖可以', '王不败', '王劳模', '王废材', '王可以']
