Question

我需要帮助解决这个问题

我使用python 2.7

cat r0_v4-aver.csv

134323

cat u3_v4-aver.csv

127757

cat u3_v4-aver.csv

153126

f_r0v4 = "/home/ubuntu/script/prtg/report-wyze/csv/r0_v4-aver.csv"
f_u3v4 = "/home/ubuntu/script/prtg/report-wyze/csv/u3_v4-aver.csv"
f_t1v4 = "/home/ubuntu/script/prtg/report-wyze/csv/t1_v4-aver.csv"
f_g1_v4 =  [ f_r0v4,f_u3v4,f_t1v4 ]
f_g1all_v4 = "/home/ubuntu/script/prtg/report-wyze/csv/g1_all_v4.csv"
o_g1_all_v4 = csv.writer(open(f_g1all_v4, 'wb' ))

for k_g1_v4 in f_g1_v4:
    o_g1_v4 = csv.reader(open(k_g1_v4, 'rb'))
    t_g1_v4 = o_g1_v4.next()
    o_g1_all_v4.writerow(t_g1_v4)

输出

我需要显示的是135285,127362,15540

不显示
134323
127757
153126

谢谢

Answer 1

尝试一下：只需替换

export class MyClass {
    private value;
    private valueSubject: Subject<any> = new Subject<any>();

    public doSomethingAsync() {
        someAsyncCall()
            .subscribe(value => {
                this.value = value;
                this.valueSubject.next(value);
            });

        return valueSubject.asObservable();
    }
}

export class MyOtherClass {
    public doSomethingElse() {
        const myObj = new MyClass();
        let myValue;

        myObj
            .doSomethingAsync()
            .subscribe(value => {
                myValue = value
            });
    }
}

使用

o_g1_all_v4.writerow(t_g1_v4)

注意：您需要创建没有csv模块的o_g1_all_v4.write(t_g1_v4 + ",")文件，例如：

o_g1_all_v4

，然后在其上使用o_g1_all_v4 = open(<filename.csv>,"w">)方法。

Answer 2

不起作用

var rg = '/[^\\](\\n)/g'
var str = 'so you can do pretty much \\nanything you want with it. \n\nAt runtime Carota has'

AttributeError：'_csv.writer'对象没有属性'write'

Answer 3

o_g1_all_v4 = (open(f_g1all_v4, 'w'))
    o_g1_v4 = csv.reader(open(k_g1_v4, 'r'))
        t_g1_v4 = o_g1_v4.next()
        o_g1_all_v4.write(str(t_g1_v4 + ','))

cat csv / g1_all_v4.csv

['134323']，['127757']，['153126']，

会发生什么？

Python使用循环获取CSV列表
