将变量和换行符放入Python的打印语句中

Question

此代码中不断出现语法错误。有人可以在这里看到任何格式错误吗？

for i in range (10,-1,-1):
    b="green bottles sitting on the wall"
    print(i,b,\n,i,b,\n,"And if one green bottle should accidentally fall"\n"There will be",i,b)

Answer 1

这是已更正的内容：

$ awk -F'|' 'NR==FNR{a[$1]++;a[$2]++;next} a[$1]*a[$2]>1' file{,}

Answer 2

应该是这样的：

print(i,b,"\n",i,b,"\n","And if one green bottle should accidentally fall\nThere willbe",i,b)

\n应该是一个字符串。反斜杠（\）字符用于转义具有特殊含义的字符。
