试图通过让用户输入列数和行数来打印文本，我哪里出错了？

当我做3乘3的时候，它会给我一张由1、4、4、3张笑脸组成的列表

Answer 1

有些print是不正确的

for noofrows in range(rows): #same as range(0,row,1)
    #don't print a smiley here
    #print(":)")
    for noofcol in range(col): #same as range(0,col,1)
        print(":)",end="")
    #print an empty string instead and at the end of the loop
    print("")

Python 2中的等效代码将row作为3，将col作为3个输出
