有没有办法缩短更改某些字符串的代码？ 关闭

Question

好的，所以我有这么一大段代码，它所做的只是在个位数之前添加一个“o”。 有没有办法压缩这个？

minuteStr = '8'    

if minuteStr == '9':
    minuteStr = 'o ' + minuteStr
elif minuteStr == '8':
    minuteStr = 'o ' + minuteStr
elif minuteStr == '7':
    minuteStr = 'o ' + minuteStr
elif minuteStr == '6':
    minuteStr = 'o ' + minuteStr
elif minuteStr == '5':
    minuteStr = 'o ' + minuteStr
elif minuteStr == '4':
    minuteStr = 'o ' + minuteStr
elif minuteStr == '3':
    minuteStr = 'o ' + minuteStr
elif minuteStr == '2':
    minuteStr = 'o ' + minuteStr
elif minuteStr == '1':
    minuteStr = 'o ' + minuteStr

Answer 1

在个位数前添加“o”

minuteStr = '8'
if len(minuteStr) == 1 and minuteStr.isdigit():
   minuteStr = 'o ' + minuteStr
