I have managed so far to read my Kubernetes pod logs into lines with Python
with open('2215.log','r') as f :
for line in f.readlines():
print (line)
Got this output

I want to separate them into
TIMESTAMP+'stderr F'+ the rest
How to do that?
>Solution :
split takes a second argument to define the maxsplits, i.e.:
with open('2215.log','r') as f :
for line in f.readlines():
print(line.split(' ', 2))
Will give you 2 splits (therefore give you 3 parts). Note you have to explicitly define the separator too when using this.
