Python TypeError: cannot concatenate 'str' and 'int' objects when trying to print

Question

我运行在尝试制作一个计算器时遇到了这个问题，它需要几秒钟的时间并在 minutes:seconds 中给出时间的输出，并且它会产生这个错误

这是我的代码：

timeInSeconds = 1823
timeInMinutes = timeInSeconds / 60
timeInRest = timeInSeconds % 60

str(timeInMinutes)
str(timeInRest)

print("Your time in minutes and seconds is " + timeInMinutes + ":" + timeInRest)

Answer 1

改变

print("Your time in minutes and seconds is " + timeInMinutes + ":" + timeInRest)

至

print("Your time in minutes and seconds is " + str(timeInMinutes) + ":" + str(timeInRest))

Answer 2

您忘记重新分配新值：

timeInSeconds = 1823
timeInMinutes = timeInSeconds / 60
timeInRest = timeInSeconds % 60

timeInMinutes = str(timeInMinutes)
timeInRest = str(timeInRest)

print("Your time in minutes and seconds is " + timeInMinutes + ":" + timeInRest)

基本上是这样做的：

str(timeInMinutes)

并不意味着您的 TimeInMinutes 变量现在是一个字符串。您必须像这样重新分配它：

timeInMinutes = str(timeInMinutes)

我相信这就是你想要做的。

但是，保留 int 值以备后用可能会有用。如果是这种情况，您可以像这样创建新变量：

timeInMinutesStr = str(timeInMinutes)
timeInRestStr = str(timeInRest)

print("Your time in minutes and seconds is " + timeInMinutesStr + ":" + timeInRestStr)

或者，您可以直接在打印中转换值，以避免必须分配以后可能不会使用的新变量：

print("Your time in minutes and seconds is " + str(timeInMinutes) + ":" + str(timeInRest))
