python和python这2个是一样的，并没有区别。

很显然，两个一样的物品或者内容并不存在不同，提问的第一个元素与第二个元素是一模一样，本质上讲就是一个东西、一件事情。

建议把前后两个要做对比的元素描述清楚，比如python2.X和Python3.X有什么区别，才能正确结论。

六、少儿python和成人python的区别？

没有区别。首先Python它的语言方式与自然语言很是接近，具有很好的可阅读性，当然理解起来也就不是晦涩难懂，更容易让人亲近。所以非常适合小朋友学习和初次学习代码类编程程序员学习。

其次它功能强大，特别是在科学计算，人工智能领域上更是天赋异禀。由于Python语言的简洁性、易读性以及可扩展性，所以非常适合孩子过渡到代码类编程语言的学习。

七、python与Python竞赛班的区别？

Python与Python竞赛班的区别主要体现在以下几个方面：

1. 目标群体不同：Python是一门编程语言，可以用于各种编程任务和项目的开发，适合任何想要学习编程的人群；而Python竞赛班则主要面向对Python编程有一定基础，并想要通过参加编程竞赛提高技能水平的学生。

2. 内容深度不同：Python作为一门编程语言，学习的内容包括语法、数据类型、函数、面向对象编程等基础知识，以及各种库和框架的使用；而Python竞赛班会更加侧重于竞赛相关的知识和技巧，例如算法、数据结构、竞赛策略等。

3. 学习方式不同：Python可以通过自学、在线教程、教材等多种方式学习；而Python竞赛班则通常是通过参加线下班级培训的形式，由专业的老师进行指导和培训。

总而言之，Python是一门广泛适用于各种编程任务的语言，学习的内容相对全面；而Python竞赛班则更加专注于竞赛所需的知识和技巧，适合有一定编程基础并且对竞赛感兴趣的学生。

八、python"or"的问题？

用or关联的两个元素，如第一个元素为真，那么与之关联的另一个元素则不会进行计算。

九、python的由来？

回答：1989年圣诞节期间，在阿姆斯特丹，Guido为了打发圣诞节的无趣，决心开发一个新的脚本解释程序，作为ABC 语言的一种继承。之所以选中Python（大蟒蛇的意思）作为该编程语言的名字，是取自英国20世纪70年代首播的电视喜剧《蒙提.派森的飞行马戏团》（Monty Python's Flying Circus）。 ABC是由Guido参加设计的一种教学语言。就Guido本人看来，ABC 这种语言非常优美和强大，是专门为非专业程序员设计的。但是ABC语言并没有成功，究其原因，Guido 认为是其非开放造成的。Guido 决心在Python 中避免这一错误。同时，他还想实现在ABC 中闪现过但未曾实现的东西。 就这样，Python在Guido手中诞生了。

十、python%的用法？

在Python中，百分号符号（%）是一个运算符，用于格式化字符串和进行字符串插值。以下是%运算符的一些用法：

字符串插值：可以使用%运算符将变量插入到字符串中。例如：

name = 'Alice'

age = 25

print('My name is %s and I am %d years old.' % (name, age))

这将输出：My name is Alice and I am 25 years old.

在这个例子中，%s和%d是占位符，分别代表字符串和整数变量。这些占位符被替换为变量name和age的值。

格式化字符串：可以使用%运算符来格式化字符串。例如：

x = 3.1415926

print('%.2f' % x)

这将输出：3.14

在这个例子中，%.2f是一个格式化字符串，表示保留小数点后两位。%运算符将x变量插入到这个字符串中，并根据格式化字符串的指示将其格式化。

字典插值：可以使用%运算符将字典中的值插入到字符串中。例如：

person = {'name': 'Bob', 'age': 30}

print('My name is %(name)s and I am %(age)d years old.' % person)

这将输出：My name is Bob and I am 30 years old.

在这个例子中，%(name)s和%(age)d是字典占位符，分别代表字符串和整数变量。%运算符将person字典插入到这个字符串中，并根据占位符的指示将其格式化。

以上是%运算符的一些用法。需要注意的是，虽然%运算符在Python中仍然可用，但在Python 3.x中已经有了更好的格式化字符串的方式，即使用f-strings。
