Can you explain how synchronous code executes and how it manages the sequence of operations?

Synchronous programming code executes sequentially, line by line. Each operation must complete before the next one begins. This means that the program blocks on the current operation until it finishes.
For example, if there is a call to a file reading function in the code, the program will wait until the file is fully read before moving to the next line.
This approach simplifies understanding and debugging but can lead to delays if operations take a long time (such as network requests or input/output).
Example in Python:
print("Start")
result = open('file.txt').read() # Blocks execution until the file is read
print("File read")
Here, "File read" will only be printed after the file reading is complete.
