Python中常见内置函数的用法合集

character = 'ä'
ascii_representation = ascii(character)
print(ascii_representation)  # 输出：'\xe4'

fruits = ['apple', 'banana', 'cherry']
for index, fruit in enumerate(fruits):
 print(f"Index: {index}, Fruit: {fruit}")

name = input("请输入您的姓名：")
print(f"您好，{name}！")

number = 10
oct_string = oct(number)
print(oct_string)  # 输出：'0o12'

class MathUtil:
 @staticmethod
 def add(a, b):
     return a + b
result = MathUtil.add(5, 3)
print(result)  # 输出：8

number = 10
bin_string = bin(number)
print(bin_string)  # 输出：'0b1010'

expression = "5 + 3"
result = eval(expression)
print(result)  # 输出：8

number_str = "10"
integer = int(number_str)
print(integer)  # 输出：10
hex_str = "1a"
hex_integer = int(hex_str, 16)
print(hex_integer)  # 输出：26

file = open("example.txt", "r")
content = file.read()
print(content)
file.close()

number = 10
number_str = str(number)
print(number_str)  # 输出：'10'

value = 0
bool_value = bool(value)
print(bool_value)  # 输出：False

code = """
for i in range(5):
 print(i)

exec(code)

number = 10
is_integer = isinstance(number, int)
print(is_integer)  # 输出：True

character = 'A'
ascii_value = ord(character)
print(ascii_value)  # 输出：65

numbers = [1, 2, 3, 4, 5]
total = sum(numbers)
print(total)  # 输出：15
