如何在python 3版本中使用此代码？ [重复]

Question

我想在 python 3 中运行此代码，但我不能。每当我尝试运行该代码时，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)

Answer 1

在

print

function 调用两边加上括号。

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。

在Python3中，

print

是一个函数，所以它的参数需要用括号括起来。
