Question

我尝试读取文件的内容并将其保存为变量，并尝试将其转换为float和-

-3

在此编辑代码：（更改的目录名称）年龄

Traceback (most recent call last):
  File "/Users/username/wageCalculator.py", line 26, in <module>
    writeTotal.write(str(float(total)+float(getBal)))
TypeError: float() argument must be a string or a number, not '_io.TextIOWrapper

我尝试将其转换为字符串，但它给了我同样的错误。

任何人都能找到答案，那就太好了。：p

编辑：我已经尝试过getBal和readBal，而readBal给了我这个错误：

import time
while True:
    wage = 5
    moneyPerSecond=(int(wage)/3600)
    moneyPerMinute=(int(wage)/60)
    print('Your wage per second is: $'+str(moneyPerSecond))
    print('Please input the amount of minutes you worked. It must be a whole number.')
    minutesWorked = input()
    minuteWage = int(minutesWorked)*float(moneyPerMinute)
    print('Please input the amount of seconds you worked. It can be a decimal.')
    secondsWorked = input()
    secondWage = float(secondsWorked)*float(moneyPerSecond)
    print('Your total is: $' + str(float(minuteWage)+float(secondWage)))
    total = float(minuteWage)+float(secondWage)
    getBal = open('/Users/username/balance.txt','r+')
    readBal = getBal.read()
    getBal.close()
    print('Current balance: $' + str(readBal))
    print('Do you want to add this to your balance?')
    print('Key in "y" for yes or "n" for no and press enter:')
    yesOrNo = input()
    if yesOrNo=='y':
        open('/Users/username/balance.txt','w').close
        writeTotal = open('/Users/username/balance.txt' ,'a')
        writeToLog = open('/Users/username/balanceLog.txt','a')
        writeToLog.write(str(total))
        writeTotal.write(str(float(total)+float(readBal)))
        writeTotal.close()
        writeToLog.close()
    elif yesOrNo=='n':
        print('Reseting...')
        time.sleep(1)
    else:
        print('Please try again.')

错误中的代码行与发布的代码不匹配：

writeTotal.write(str(float(total)+float(getBal)))

vs。

writeTotal.write(str(float(total)+float(readBal)))

大概您打算使用float(readBal)。
