"a function call, connected by arithmetic operators" can be translated as "一个函数调用，由算术运算符连接"。

For an elaboration and an example, here it is:

Elaboration (说明): In an arithmetic expression, a function call refers to the use of a mathematical function within the expression. This function is usually defined elsewhere in the code and can take one or more arguments. When a function call is connected by arithmetic operators, it means that the result of the function is combined with other constants, variables, or expressions using arithmetic operations.

Example (示例): Let's consider a simple arithmetic expression with a function call:

Suppose we have a function named "multiply" that multiplies two numbers. The function is defined as follows:

def multiply(x, y):
    return x * y

Now, in an arithmetic expression, you can use this function as follows:

result = multiply(3, 5) + 2

In this example, "multiply(3, 5)" is a function call, and it returns the result of multiplying 3 and 5, which is 15. This result is then connected to the constant 2 using the arithmetic operator "+". So, the overall expression evaluates to 15 + 2, which is equal to 17.

如果您看以下（仅用于演示而进行了简化）示例：

def add_numbers(a, b):
    return a + b  # 返回一个整数

result = 5 + add_numbers(3, 7)
print(result)

如果您看result = 5 + add_numbers(3, 7)：Python会解释为“运行函数'add_numbers'，获取返回的结果然后将其加到5”。因此，一旦完全评估，该行在此示例中实际上变成了：

result = 5 + 10

换句话说，您可以将其视为Python将您的代码中的函数调用替换为该函数的返回值，然后执行这两个值的加法。

def add_numbers(a, b):
    return a + b  # Returns an integer

result = 5 + add_numbers(3, 7)
print(result)
