Question

我的文本文件为

01,Jay,Sharma
02,Rushi,Patel

我想将此文本文件读取为数组，并希望输出为

student no : 01
Name : Jay
Surname : Sharma
student no : 02
Name : Rushi
Surname : Patel

实际上，我是Python的新手，我能够将其读取为数组，但我想要准确的输出，请任何人都可以帮助我。

class RowReader:
    def fileRead(self,filepath):
        textfile = open(filepath, 'r')
        data = []
        for line in textfile:
            row_data = line.strip("\n").split(',')
            print(row_data)

file = RowReader()
file.fileRead(file_path)

提前谢谢

Answer 1

有一个库可以在Python中读取csv文件：csv。您可以轻松地读取csv文件。

import csv

data = []
with open("filename.csv", "r") as f:
    reader = csv.reader(f)
    for line in reader:
        data.append(line)

for d in data:
    print("student no : {}\nName : {}\nSurname : {}".format(
        d[0], d[1], d[2]))

Answer 2

您可以尝试如下操作：

class RowReader:
    def fileRead(self,filepath):
        textfile = open(filepath, 'r')
        data = []
        for line in textfile:
            row_data = line.strip("\n").split(',')
            if len(row_data) == 3:
                print("student no : {}\nName : {}\nSurname : {}".format(
        row_data[0], row_data[1], row_data[2]))

file = RowReader()
file.fileRead(file_path)

我添加了一个if条件，只是为了检查row_data列表中的值数量。如果存在一些缺失值，可以对其进行相应处理。

public class playercontrol: MonoBehaviour {

  public void Update() {
    playera.transform.Translate((Vector3.forward * speed * Time.deltaTime));
    Debug.Log("speed" + speed);

    if (check == false) {
      if (Input.GetMouseButtonDown(0)) {
        Debug.Log("left button");

        firstPressPos = new Vector2(Input.mousePosition.x, Input.mousePosition.y);
      }

      if (Input.GetMouseButtonUp(0)) {

        secondPressPos = new Vector2(Input.mousePosition.x, Input.mousePosition.y);

        currentSwipe = new Vector2(secondPressPos.x - firstPressPos.x, secondPressPos.y - firstPressPos.y);

        currentSwipe.Normalize();

        //swipe left
        if (currentSwipe.x < -1.0 f && currentSwipe.y > -0.5 f && currentSwipe.y < 0.5 f) {
          Debug.Log("left swipe");
          if (transform.position.x > -9 f) {
            spos = transform.position;
            Debug.Log("spos" + spos);
            endpos = new Vector3(transform.position.x - 9 f, transform.position.y, transform.position.z + ((speed * 2) / 20));
            Debug.Log("speed......... ......." + ((speed * 5) / 20));
            transform.rotation = Quaternion.Euler(0, -10.0 f, 0);
            check = true;
            //endpos * (Time.deltaTime*0.5f);
            //  Time.timeScale = 0.5f;
            //                          to.rotation = Quaternion.Euler (0, 0, 0);
          }

        }

        //swipe right
        if (currentSwipe.x > 1.0 f && currentSwipe.y > -0.5 f && currentSwipe.y < 0.5 f) {
          Debug.Log("right swipe");
          if (transform.position.x < 9 f) {
            Debug.Log("spos1" + spos);
            spos = transform.position;
            endpos = new Vector3(transform.position.x + 9 f, transform.position.y, transform.position.z + ((speed * 2) / 20));
            Debug.Log("speed1......... ......." + ((speed * 5) / 20));
            transform.rotation = Quaternion.Euler(0, 10.0 f, 0);
            check = true;
            //  Time.timeScale = 0.5f;
            //  to.rotation = Quaternion.Euler (0, 0, 0);
          }
        }
      }
    }

    if (check == true) {
      time += 10 * Time.deltaTime;
      transform.position = Vector3.Lerp(spos, endpos, time);
      //    transform.rotation = Quaternion.Lerp (from.rotation, to.rotation, time);

      if (time > 1) {
        transform.rotation = Quaternion.Euler(0, 0, 0);
        //Time.timeScale = 1.0f;    
        //playera.transform.Rotate (0, 0, 0);
        //transform.Rotate (0, 0, 0);
        check = false;
        time = 0;
      }
    }
  }
}

class RowReader:

    def fileRead(self,filepath):
        textfile = open(filepath, 'r')
        data = []
        for line in textfile:
            row_data = line.strip("\n").split(',')
            data.append(row_data)
            #print(row_data)
        for x in range(len(data)):
            print("student no :",data[x][0])
            print("Name :",data[x][1])
            print("Surname :",data[x][2])
        #print(data)
file = RowReader()
file.fileRead("new.txt")

这是我们代码中的更改

Answer 5

您可以在循环中使用此问题

import csv

output=[]

with open('filename.csv','r') as file:
    fileCsv = csv.reader(file)
    for row in file:
        rowData = row.strip('\n').split(',')
        output.append(rowData)
    file.close()

for anotherRow in output:
    print('student number : %s\nName : %s\nSurname : %s'%(anotherRow[0],anotherRow[1],anotherRow[2]))

输出将是

student number : "01
Name : Jay
Surname : Sharma"
student number : "02
Name : Rushi
Surname : Patel"

我想将逗号分隔的文件读取为Python中的数组
