Python is in some respects similar to C, but is a language that is significantly higher in level. Without using any external libraries/modules, you can get permutations and combinations very quickly.Greg Bernhardt said:Mark, how would you compare Python with other similar languages?
# dotprod.py -- find the dot product of two vectors
import operator
def dotprod(u, v):
return sum(map(operator.mul, u, v))
u = [1, 2, -1, 4, 2, 1, -2, 6]
v = [1, 4, -1, 0, 1, 1, -2, 4]
ans = dotprod(u, v)
print("Result is: ", ans)
#list_comp.py -- simple example of list comprehension
my_list = [x for x in range(256) if x % 16 == 0]
print(my_list)
Comments are used to provide additional information or explanations about the code. They are not executed by the computer and are only meant for humans to understand the code better.
To add comments in Python, use the hash symbol (#) before the comment. Everything after the hash symbol will be ignored by the computer.
Yes, comments can be used for debugging by providing relevant information about the code and its purpose. This can help in understanding and finding errors in the code.
The Python debugger allows you to step through the code line by line and inspect the values of variables at each step, making it easier to identify and fix errors. In contrast, print statements require you to manually add them throughout the code to check for values, which can be time-consuming and tedious.
To exit the Python debugger and continue running the code, use the 'continue' command or press 'c' followed by the enter key. This will continue execution until the next breakpoint or the end of the code.
