To illustrate, the example below shows a toy function that checks the length of a string object: Python >>> def validate_length(string): ... if (n := len(string)) < 8: ... print(f"Length {n} is too short, needs at least 8") ... else: ... print(f"Length {n} is...
Python modules are libraries of code and you can import Python modules using the import statements. 让我们从一个简单的案例开始。 Let’s start with a simple case. 我们将通过说“导入数学”来导入数学模块。 We’re going to import the math module by saying "import math". 该模块具有多个功能。

A single-line comment starts with the # symbol. Everything after # on the same line is ignored by Python. It is usually used to give information about a single line of code. Example: Python 1 2 3 4 5 6 7 8 9 10 11 12 # Assign course name course_name = "Intellipaat Python Co...

Everything these three functions do can be replicated with the newer run() function. The older API is mainly still there for backwards compatibility, and you won’t cover it in this tutorial. There’s also a fair amount of redundancy in the subprocess module, meaning that there are various...
The preceding code trusts that everything after the colon (:) is a temperature. The string is split at:, which produces a list of two items. Using[-1]on the list returns the last item, which is the temperature in this example.
