CSV文件和TypeError：类似字节的对象

Question

我在编写CSV文件时遇到问题。每次我使用python编写CSV文件时，突然Here is the CSV file with blank space的每一行都有空白。因此，我在互联网上寻找解决方案。然后某个网站说我只需要将“ w”更改为“ wb”，但是在尝试运行该程序后，就会发生错误。

错误：TypeError：需要一个类似字节的对象，而不是'str'

我的代码：

seat =[]
csvfile = open('coba.csv') 
seating = csv.reader(csvfile)
for line in seating:
    seat.append(line)

print("Buy seat ?")
answer_1 = input("Answer : ")
if (answer_1 == "yes"):
    answer_2 = input("Enter preferred seat: ")
    if (answer_2 == "A1"):
        row = 1
        column = 0
        seat[row][column] = "X"
        writer = csv.writer(open('coba.csv', 'wb'))
        writer.writerows(seat)
        for line in seat:
            print(' | '.join(line))

CSV文件：

[Business]
A1,A2,A3,A4,A5
B1,B2,B3,B4,B5
[Economy]
C1,C2,C3,C4,C5
D1,D2,D3,D4,D5

Answer 1

您正在读“ r”，正在写“ wb”

您要么更改每个元素的数据类型，要么简单地

将wb更改为w，就可以了

完整代码

import csv

seat =[]
csvfile = open('coba.csv')
seating = csv.reader(csvfile)
for line in seating:
    seat.append(line)

print("Buy seat ?")
answer_1 = input("Answer : ")
if (answer_1 == "yes"):
    answer_2 = input("Enter preferred seat: ")
    if (answer_2 == "A1"):
        row = 1
        column = 0
        seat[row][column] = "X"
        writer = csv.writer(open('coba.csv', 'w'))
        writer.writerows(seat)
        for line in seat:
            print(' | '.join(line))

输出

Buy seat ?
Answer : yes
Enter preferred seat: A1
[Business]
X | A2 | A3 | A4 | A5
B1 | B2 | B3 | B4 | B5
[Economy]
C1 | C2 | C3 | C4 | C5
D1 | D2 | D3 | D4 | D5

Answer 2

在您的import { WINDOW } from '@ng-toolkit/universal'; import { Component, OnInit , Inject} from '@angular/core'; @Component({ selector: 'app-home', templateUrl: './home.component.html', styleUrls: ['./home.component.scss'] }) export class HomeComponent implements OnInit { constructor( @Inject(WINDOW) private window: Window, ) { } ngOnInit() { this.startCarousel(); } startCarousel() { this.sectionTwoInterval = setInterval(() => { this.next(1); }, 5000); this.sectionFourInterval = setInterval(() => { this.next(2); }, 5000); } goToSlide(carousel: number, slide: number) { switch (carousel) { case 1: clearInterval(this.sectionTwoInterval); this.sectionTwoActive = slide; break; case 2: clearInterval(this.sectionFourInterval); this.sectionFourActive = slide; break; } } next(carousel: number, stop?: boolean) { if (stop === true) { this.stopInterval(carousel); } switch (carousel) { case 1: if (this.sectionTwoActive !== this.sectionTwoImages.length - 1) { this.sectionTwoActive++; } else { this.sectionTwoActive = 0; } break; case 2: if (this.sectionFourActive !== this.sectionFourImages.length - 1) { this.sectionFourActive++; } else { this.sectionFourActive = 0; } break; } } back(carousel: number, stop?: boolean) { if (stop === true) { this.stopInterval(carousel); } switch (carousel) { case 1: if (this.sectionTwoActive !== 0) { this.sectionTwoActive--; } else { this.sectionTwoActive = this.sectionTwoImages.length - 1; } break; case 2: if (this.sectionFourActive !== 0) { this.sectionFourActive--; } else { this.sectionFourActive = this.sectionFourImages.length - 1; } break; } } stopInterval(carousel: number) { switch (carousel) { case 1: clearInterval(this.sectionTwoInterval); break; case 2: clearInterval(this.sectionFourInterval); break; } } 调用中使用newline关键字参数，

open()
