I use python and am currently an Expert on codeforces. I come across an unfair tle issue about once every months or so, when practicing. Didn’t really face any issues in a challenge till date. It’s honestly quite chill, if your algorithm’s right, it’ll pass 98% of the time. Answer from WubbaLubbaDubDub26 on reddit.com

CP with Python Essentials - Codeforces
It has been a common misconception amongst Competitive Programming(hereafter CP) beginners, that Python is a slower language than C++ and they must learn C++ for CP. Some of the rumours I've come across were Python submissions giving TLE but the same algorithm implemented in C++ cleared the test cases.

What's better for competitive programming, is it Java, Python, or JavaScript?
I’d do Java. I use python mainly and I love it, but there are some downsides to it. One positive thing about it is that everything is like 10x easier to implement and those 1 liners are sweet lol. So much builtin power & libraries. However, I think in the process of doing leetcode & preparation, Java would be more beneficial to understanding of data structures & OOP. Java is a pretty popular language as well, and having a good understanding of it, I think would more readily translate down to javascript later down the line than I think python would.

Python or C++ for competitive programming?

u definitely would write code in python faster and it definitely would be slower than c++ in most cases

but since code speed doesnt matter to u all that much python is probably the better option for u

You can use python But it is highly suggested you switch to c++ as the whole community is built around it and following resources will be much easier

Competitive Programming PyPy 3-64 Template for Beginners - Codeforces
Being a beginner in CP I found it very hard to come up with faster solutions in Python (the only language I am good at) and recently while going through some Git Repositories I found out a Python (PyPy) template for Competitive Programming. But since that Repo was outdated, I decided to make my own version of the template after doing some study on the previous template. So here I am presenting to you all my version of the Python Template which runs fine in all versions of Python in both Codechef and Codeforces.

Issue with Python ! - Codeforces
But there are a lot of languages that CodeForces supports, so either is stops supporting them in contests or has a defined time limit for each question serperately for each problem because the current scenario won't allow any other language to progress in the competitive world ! And just to counter the logic being given by some people that the fastest should be used, then why aren't we all using Assembly ? ! Same is what I want to say for the case of Python !

It looks like input is provided in stdin and output should be written to stdout, so your solution should look like that:

n, k = input().split()
n = int(n)
k = int(k)

for i in range(k):
    last = n % 10
    if last == 0:
        n = n/10
    else:
        n = n - 1
print(int(n))

Note: I didn't check your solution, just rewrote it in simplest way to illustrate the method.

Why would someone use Python or Java instead of C++ for Codeforces? - Codeforces
Shorter code? I seriously doubt so. At least compare to Java, C++ is shorter. Compared to Python, unless you want to couple everything into one unreadable line, then C++ should not be very longer.
