最后,我们需要测试我们的函数,确保它的正确性: # 测试函数try:print(str_to_bool("yes"))# 输出: Trueprint(str_to_bool("no"))# 输出: Falseprint(str_to_bool("1"))# 输出: Trueprint(str_to_bool("0"))# 输出: Falseprint(str_to_bool("true"))# 输出: Trueprint(str_to_bool("false")...
boolean_value = strtobool(string_value) 2. Convert String to Boolean Using bool() Function You can use thebool()function to convert a string to a boolean. For example, creating a string named"string_value"and passing it intobool()function will convert the string"Welcome To SparkByExamples"...
The following code uses the bool() function to convert String to Boolean in Python.1 2 3 4 5 str1 = "Cricket" x = bool(str1) print(x)Output:True This function gives a True value when the argument is non-empty, while it always returns a False value for empty arguments....

Python 中的数据类型转换 将一种 Python 数据类型转换为另一种数据类型的过程称为类型转换。当需要确保数据与特定函数或操作兼容时，可能需要进行类型转换。如何在 Python 中进行类型转换Python 提供了四个可用于类型转换的内置函数。这些函数是：str()、int()、float()、bool()。这些函数分别返回字符串、整数、浮点...

In Python, "False" (i.e. string false) is not type converted to boolean False automatically. In fact, it evaluates to True: print(bool('False')) # True print(bool('false')) # Tr
