How to use PyCharm to run a single line of code

In PyCharm, there are two ways to run a single line of code:

Method 1 : Use keyboard shortcuts

Windows/Linux: Ctrl Enter
macOS: Cmd Enter

Method 2: Use the menu Bar

Click "Run" in the menu bar
Select "Run Selected Rows"

Detailed steps:

Select the line to run: Use the mouse or keyboard cursor to select the line of code to run.
Execute shortcut keys or menu options: Use one of the shortcut keys or menu options mentioned above.
View output: PyCharm will display the output of your code in the Output panel.

Note:

If the selected line contains the definition of a function or class, PyCharm will run the entire function or class instead of just Run this line.
PyCharm will display an error message for lines containing syntax errors.
Keyboard shortcuts can be changed in PyCharm's "Settings".

How can you perform mathematical operations on entire NumPy arrays efficiently?May 06, 2025 am 12:15 AM

Mathematical operations of the entire array in NumPy can be efficiently implemented through vectorized operations. 1) Use simple operators such as addition (arr 2) to perform operations on arrays. 2) NumPy uses the underlying C language library, which improves the computing speed. 3) You can perform complex operations such as multiplication, division, and exponents. 4) Pay attention to broadcast operations to ensure that the array shape is compatible. 5) Using NumPy functions such as np.sum() can significantly improve performance.

How do you insert elements into a Python array?May 06, 2025 am 12:14 AM

In Python, there are two main methods for inserting elements into a list: 1) Using the insert(index, value) method, you can insert elements at the specified index, but inserting at the beginning of a large list is inefficient; 2) Using the append(value) method, add elements at the end of the list, which is highly efficient. For large lists, it is recommended to use append() or consider using deque or NumPy arrays to optimize performance.
