【问题描述】：

我想让用户输入他的姓名/年龄，然后输出十年后的姓名和年龄。我是这样设置的：

    print("Let's find out how old you will be in 10 Years.\n")
    name = input("name: ")

    print("\nNow enter your age,",name,"\n")
    age = int(input("age: "))

    ageinten = age + 10

    print("\n",name,"you will be",ageinten,"in ten years.")

    input("Press Enter to close")

输出是这样的：

    Let's find out how old you will be in 10 Years.

    name: Example

    Now enter your age, Example 

    age: 20

     Example you will be 30 in ten years.
    Press Enter to close

但我希望它没有示例前面的空格：

    Example you will be 30 in ten years.
    Press Enter to close

谁能帮忙解决这个问题？

【解决方案1】：

更好地使用string formatting:

print('\n{} you will be {} in ten years.'.format(name, ageinten))

或使用sep=''，但你必须在字符串中添加尾随和前导空格。：

print("\n", name, " you will be ", ageinten, " in ten years.", sep='')

sep 的默认值是一个空格，这就是你得到一个空格的原因。

演示：

>>> name = 'Example'
>>> ageinten =  '20'
>>> print("\n",name," you will be ",ageinten," in ten years.", sep='')

Example you will be 20 in ten years.
>>> print('\n{} you will be {} in ten years.'.format(name, ageinten))

Example you will be 20 in ten years.

@user2968504 很高兴有帮助，如果对您有用，您可以 accept the answer。

【解决方案2】：

尝试只使用print() 来发出换行符。这似乎最适合您当前的风格：

print("Let's find out how old you will be in 10 Years.\n")
name = input("name: ")

print()
print("Now enter your age,",name)
print()
age = int(input("age: "))

ageinten = age + 10

print()
print(name,"you will be",ageinten,"in ten years.")

input("Press Enter to close")
