excel vba - vba - find matches cells and copy it - optimizing code -


i have col d(in sheet1 called students), col a (in sheet2 called students too)and col b(in sheet2 called age).in cold there lot of similar students name , sorting z.

i want loop col d once , if exists match students name in cola (sheet2), want copy in cold(sheet1) b column(sheet2)that matches cola(sheet2).

i sorted cold because don't want loop every similar students name. mean: if student name (for example: andrew)in cold matches student name ('andrew')in cola, copy colb(matches col a- example andrew has 15 years old) in cold(sheet1). , if string 'andrew' repeated in cold (i found in cells), don't loop again colb(sheet2), copy value first string.

for example:

(sheet1)

cold: students:     row1: andrew          row2: andrew          row3: andrew          row4: andrew          row5: andrew          row6: andrew          row7: ben          row8: ben          row9: edoardo          row10: helen          row11: leonardo          row12: leonardo          row13: robert          rown: ..

(sheet2) 

      students:  colb: age:        row1: michael          16          row2: timoth           20          row3: andrew           15          row4: edoardo          19          row5: ben              13          row6: robert           24          row7: helen            17

what want:

(sheet1) 

cold: students:         row1: 15          row2: 15          row3: 15          row4: 15          row5: 15         row6: 15          row7: 13          row8: 13          row9: 19          row10: 17          row11: 0          row12: 0          row13: 24          rown: ..

i have code finds matched students name , put age in col d(sheet1):

set rngsearch = sheets("sheet1").range("d:d") each rngsearch in drng     set rngfound = arng.find(what:=rngsearch, lookin:=xlvalues, lookat:=xlwhole,   searchorder:=xlbyrows, searchdirection:=xlnext, matchcase:=false, searchformat:=false)     'if studentname found:      if not rngfound nothing          rngsearch.offset(0, 0) = rngfound.offset(0, 1)      else          rngsearch.offset(0, 0) = "-"        end if next

can me optimize code, please?

python - Django-cities exits with "killed" -

i trying install django-cities on server 500mb ram. whenever run: manage.py cities the system exits saying killed. trying run: manage.py cities --import=country --force worked, guessing matter of running out of memory. to bypass, tried refer package local copy of cities' data file. still didn't work. any ideas on how can migrate data without having increase memory on server? based on suggestion comments, solved setting temporary swap file. if unfamiliar it, can follow these steps: set swap file touch /var/swap.img chmod 600 /var/swap.img set swap file size cd /var dd if=/dev/zero of=/var/swap.img bs=1024k count=1000 this create 1gb swap file. prepare disk image mkswap /var/swap.img activate swap memory swapon /var/swap.img once done, can turn off swap image: swapoff /var/swap.img more information on virtual memory , swap files can found here: https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-me...
