- Reading a large data file (efficiently)
Tips
- with pylab, removes the white borders:
<source lang="py"> savefig('figure.eps',format='eps',bbox_inches="tight") </source>
- equivalent of the C ternary operator ?: (test ? restrue : 'resfalse), use a tuple is possible but not transparent
<source lang="py"> (resfalse,restrue)[test] </source> prefer the inline condition testing way <source lang="py"> res = restrue if test or resfalse
- example
min = lambda x,y: x if x<y else y min(1,2) </source>
- adding a path to a directory containing your module files
<source lang="py"> import sys sys.path += [ "/home/username/bin/Python" ] </source>
- test whether a string has only digits or letters
<source lang="py"> str = '1321' str.isdigit() # returns True/False str.isalpha() # returns True/False </source>
- Nested for loops in a single line:
<source lang="py"> for n,m in [ (n,m) for n in range(10) for m in range(2) ]:
print n,m
</source>
