Question

我想从用户那里获取包含字符串的输入，将该字符串存储到变量中，然后将其写入另一个字符串行中。

我尝试使用open和.write并使用（％s）将输入添加到写入的行中。

outF = open("file.txt", "w")
string = raw_input("enter string to add!")
outF.write('string data to write (%s)', % string)
outF.close()

Answer 1

尝试一下：

outF = open("file.txt", "a") #append mode if u wish to add more data to the file later
string = raw_input("enter string to add!")
string_new="string u want to add before"+string #add strings wherever u need
outF.write(string_new)
outF.close()

Answer 2

看看这是否适合您

export class Utils {
  pushUnique<T, U>(arr: T[], obj: T, key: (o: T) => U = null, logVerbose: boolean = false): void {
    if (logVerbose === true) {
      console.log('pushUnique called');
    }

    if (typeof obj === 'object' && key === null) {
      console.warn('Object defined in pushUnique is complex, but a key was not specified.');
    } else if (typeof obj !== 'object' && key !== null) {
      console.warn('Object is not complex, but a key was specified');
    }

    const index = key !== null ? arr.findIndex(o => key(o) === key(o)) : arr.indexOf(obj);
    if (index === -1) {
      arr.push(obj);
    } else {
      if (logVerbose === true) {
        console.log('Duplicate object, not added');
      }
    }
  }
}

如何使用open和.write在同一行上将字符串+变量值写入文件？
