python-2.7

问题 I have the following query line: c.execute("""insert into apps (url)""") I have variable url that I try to append in query insert. But U get Mysql sintax error There are two field in table: id - autoincrement and url 回答1: The better question should be "How to substitute value in string?" as the query you are passing to the c.execute() is of the string format. Even better, "How to dynamically format the content of the string?" In python, to do that there are many ways: Using str.format() # Way

问题 Even though I'm very new with python, I can't understand how I haven't been able to solve this issue / take a right approach. So any help, link to a helpful tutorial is appreciated highly as I have to do this kind of stuff from time to time. I have a CSV file that I need to reformat / modify a bit. I need to store the amount of samples that the gene is in. input file: AHCTF1: Sample1, Sample2, Sample4 AHCTF1: Sample2, Sample7, Sample12 AHCTF1: Sample5, Sample6, Sample7 result: AHCTF1 in 7

问题 I am trying to set the default python in my docker container to be python3 and have set the aliases in the dockerfile. When I open the .bashrc file, they show up. As far as I can tell, it should work but the default python version is still 2.7. if I run which python, it will still point to usr/bin/python rather than python3. Same with pip. Can anyone tell me what the problem is? Here is the command I'm using to alias: RUN \ echo 'alias python="/usr/bin/python3"' >> /root/.bashrc && \ echo
