楼主用的是python3吧
print 在python2中是语句,在python3中是函数;
>> 这个用法在python2.x版本是可以的
6)去除print语句,加入print()函数实现相同的功能.同样的还有 exec语句,已经改为exec()函数
例如:
2.X: print "The answer is", 2*2
3.X: print("The answer is", 2*2)
2.X: print x, # 使用逗号结尾禁止换行
3.X: print(x, end=" ") # 使用空格代替换行
2.X: print # 输出新行
3.X: print() # 输出新行
2.X: print >>sys.stderr, "fatal error"
3.X: print("fatal error", file=sys.stderr)
2.X: print (x, y) # 输出repr((x, y))
3.X: print((x, y)) # 不同于print(x, y)!
