Where can Python Junior find a job?

Question

Career in IT

I am facing a dilemma.
Now I work as a manager: data analysis with direct MySQL queries, scripts for personal needs in Python, a small library on it for my own needs, compilation of technical specifications for IT staff.
I studied Python for a year and a little bit of other things (HTML, JS).
Ripe to be hired as a programmer.
Found a job, got an interview.
They promise to add high-load projects, untested frameworks and libraries, etc. to the frontend (AngularJS).
There are two minuses: travel time (2-2.5 hours) and salary (40% less than I get now). However, I gave my consent. With practical experience close to zero, you don’t have to choose ... I
wrote a letter of resignation at my current job.
The management said that they did not want to lose a valuable employee and would rather transfer me to the IT department.
The problem is that no one writes in Python. Consequently, I am unlikely to get an objective assessment of my work, only by indirect signs - speed, server load, etc. Plus with front-end seams, at least in the near future. Yes, and development, I think, will not be as intensive as it could be - there is no one to instruct, only on the general architecture of applications. So acquaintance with the "new" is exclusively independent.
Pros: maintaining the current salary level, travel time (15 minutes), no need to join the team and immerse yourself in the project.
Interested in the opinion of future (at any outcome) colleagues. What would you choose?
UPD. perl/php is used at the current place of work

Answer 1

Spending 2.5 hours on the road is a nightmare. Especially if you have to spend this time in the subway. Yes, even during rush hour.
Persuade the current management to hire you a mentor :-). Or spend 40% of your salary on a mentor who will watch your code for an hour a day, give advice, teach, etc.

Answer 2

Ask at a new place how often they increase salary.
Compare theoretical prospects at a new and old place at a distance of a year, two, five, just by salary.
Compare the prospects in the "market" for a junior, for a middle Estimate the
prospect of moving to the area of ​​a new job, so that it was "15 minutes" before it - does it shine for you and how much it will cost. Consider such a waste in estimates "at a distance"
