我有波纹管类型的字符串:
str = 'PE01-A1'
str2 = 'PE01-A/1'
str3 = 'PE01-A01'
我还编写了一个获取波纹管编号的函数,可以:
def get_latter_number(str):
total = len(str)
if total == 0:
return str
number = None
for i in range(total):
tmp_str = str[(total-i - 1): total]
try:
number = int(tmp_str)
except Exception as e:
break
return number
num = get_latter_number(str)
print(num) # there will be 1
我的方法有效,但是我认为它不是pythonic的,谁能告诉我如何编写更简洁的函数?
答案 0 :(得分:0)
这可以做到:
def get_latter_number(str):
for i in range(len(str)):
try:
return int(str[i: ])
except:
pass
return None
