Question

有人可以用代码帮助我，以替换用点替换字符串中的替代逗号吗？

Answer 1

如果我对您的理解正确，则可以通过以下两种方法进行操作：

通过使用public class BankOperationComputed { private final BankOperation operation; private final int delta; BankOperationComputed (BankOperation operation, int delta){ this.operation = operation; this.delta = delta; } public void startProcessing(){ System.out.println(operation.getOutput(delta)); } }模块here

BankOperation.computeBankOperation(5, 20) // returns BankOperationComputed .startProcessing(); // uses the enum under the hoods

2或简单地：

Answer 2

some_string = 'one,two,three,four,five'
new_string = ''

replace = True    # one.two,three.four,five
# replace = False # one,two.three,four.five    

for i in some_string:
    if i == ',' : 
        if replace :
            new_string += '.'
        else:
            new_string += ','

        replace = not replace # logic for alternating

    else:
        new_string += i

print(new_string) # one.two,three.four,five


#----------------------------------------------------

some_string = 'one,two,three,four,five,six'
new_string = ''.join([s+',' if i%2 == 0 else s+'.' for i,s in enumerate(some_string.split(','))])

print(new_string.strip(',').strip('.')) #one,two.three,four.five,six
