我试图计算以下数据框中每种犯罪的百分比：
Violent Murder Larceny_Theft Vehicle_Theft
Year
1960 288460 3095700 1855400 328200
1961 289390 3198600 1913000 336000
1962 301510 3450700 2089600 366800
1963 316970 3792500 2297800 408300
1964 364220 4200400 2514400 472800
因此，我应首先计算每年的犯罪总数，然后用它来计算每种犯罪的百分比。我正在尝试以下方法：
> perc = (crime *100) / crime.sum(axis=1)
有什么想法？ 谢谢！
