Python入门 - 类型转换

int, float

print(int(1.2))  # 1
print(int("1"))  # 1
print(int("0b11", 2))  # 3
print(int("27", 8))  # 23
print(int("0xF", 16))  # 15
print(int("0x1F", 16))  # 31

print(float("1.2"))  # 1.2

 

进制转换

print(oct(10)) # 0o12
print(hex(12)) # 0xc
print(bin(3)) # 0b11

 

bool

print(bool(1)) # True
print(bool(0)) # False
print(bool(2)) # True
print(bool(-1)) # True
print(bool(-2)) # True

 

字符串

print(str(1)) # "1"
print(str(1.2)) # "1.2"
print(str(True)) # "True"
print(str([1, 2, 3])) # "[1, 2, 3]"
tuple_1 = (1, "a")
print(str(tuple_1)) # "(1, 'a')"
