如何在 python 3 版本中使用此代码？ [复制]

Question

我想在 python 3 中运行此代码，但我不能。每当我尝试运行代码时，我都会收到无效的语法错误。

age = 20
name = 'Swaroop'
print '{} was {} years old when he wrote this book'.format(name, age)
print 'Why is {} playing with that python?'.format(name)

请帮帮我。

谢谢。

Answer 1

在print 函数调用周围加上括号。

print('{} was {} years old when he wrote this book'.format(name, age))
print('Why is {} playing with that python?'.format(name))

在 Python2 中，print 是一个语句，不需要括号。

In Python3, print is a function，因此它的参数需要括号。
