python处理的例子
例子一（咖啡列表的处理）
把
coffee_list = [ '32Latte', '_Americano30','/34Cappuccino', 'Mocha35']
输出为：
1 Latte
2 Americano
3 Cappuccino
4 Mocha
def clean_list(lst):
cleaned_list = []
for item in lst:
for c in item:
if c.isalpha() != True:
item = item.replace(c,'')
cleaned_list.append(item)
return cleaned_list
coffee_list = [ '32Latte', '_Americano30','/34Cappuccino', 'Mocha35']
cleaned_list = clean_list(coffee_list)
for k, v in zip(range(1, len(cleaned_list)+1),cleaned_list):
print(k, v)
# 输出: 1 Latte
# 2 Americano
# 3 Cappuccino
# 4 Mocha
两个循环，第一个循环是列表，第二个循环是字符串。
item='32Latte'
for c in item:
if c.isalpha() != True:
item = item.replace(c,'')
print(item)
# print(c)
# 输出 Latte
