python int转str

在Python中，可以使用`str()`函数将整数转换为字符串。以下是一个例子：

num = 123
str_num = str(num)
print(str_num)  # 输出 "123"

在这个例子中，我们将整数`123`赋值给变量`num`，然后使用`str()`函数将其转换为字符串，并将结果赋值给变量`str_num`。最后，我们使用`print()`函数输出了转换后的字符串。

As an AI language model, I can provide a brief explanation of int, float, and str in Python.

- int: An int is a data type in Python that represents whole numbers. It can be positive or negative, but it cannot have a decimal point. For example, 1, 2, 3, -4, and 0 are all integers.

- float: A float is a data type in Python that represents numbers with decimal points. For example, 1.2, 3.14159, and -0.5 are all floats.

- str: A str is a data type in Python that represents a string of characters, such as letters, numbers, or symbols. Strings are typically enclosed in quotes, either single or double. For example, "hello", 'world', "123", and "!!!" are all strings.

python str转int

要将字符串转换为整数，可以使用Python内置的`int()`函数。你可以通过将字符串作为参数传递给`int()`函数来实现转换。例如：

str_num = "123"
int_num = int(str_num)
print(int_num)  # 输出：123

另外，如果字符串不是有效的整数，转换过程会引发`ValueError`异常。你可以使用`try-except`语句来捕获该异常并进行适当的处理。例如：

str_num = "abc"
try:
    int_num = int(str_num)
    print(int_num)
except ValueError:
    print("无法将字符串转换为整数")

在这个例子中，由于字符串`"abc"`不是有效的整数，所以会输出"无法将字符串转换为整数"。
