Python 中的通用函数类型

Python中的通用函数类型

python
# 导入math模块
import math
# 计算平方根
num = 16
sqrt_num = math.sqrt(num)
print("16的平方根为：", sqrt_num)
# 计算绝对值
num = -10
abs_num = abs(num)
print("-10的绝对值为：", abs_num)
# 进行取整操作
num = 3.14
floor_num = math.floor(num)
ceil_num = math.ceil(num)
print("3.14的向下取整为：", floor_num)
print("3.14的向上取整为：", ceil_num)

python
# 字符串拼接
str1 = "Hello"
str2 = "World"
result = str1 + " " + str2
print(result)
# 字符串截取
str = "Python Programming"
sub_str = str[0:6]
print(sub_str)
# 字符串替换
str = "I like apples"
new_str = str.replace("apples", "oranges")
print(new_str)
# 字符串大小写转换
str = "Hello"
upper_str = str.upper()
lower_str = str.lower()
print("大写字符串：", upper_str)
print("小写字符串：", lower_str)

python
# 列表添加元素
fruits = ["apple", "banana", "orange"]
fruits.append("grape")
print(fruits)
# 列表删除元素
fruits.remove("banana")
print(fruits)
# 列表排序
numbers = [5, 2, 8, 1, 9]
numbers.sort()
print(numbers)
# 列表反转
numbers.reverse()
print(numbers)
