Dambudziko guru nekopi faira rakasanganiswa hdfs nderekuti rinogona kunonoka.
import shutil shutil.copyfile("/hdfs/path/to/file", "/local/path/to/file")
Iyi kodhi mutsara inopinza iyo shutil module uye yobva yashandisa iyo copyfile basa kubva iyo module kukopa faira kubva kuHDFS kune yemuno faira system.
Chii chinonzi hdfs
HDFS ndeye yakagoverwa faira sisitimu inopa scalable, yakasimba, uye yakavimbika chengetedzo yemaseti makuru edata. Yakanyorwa muJava uye inomhanya pachikuva cheJava.
Nzira dzekubatanidza mafaira
Pane nzira shoma dzekubatanidza mafaera muPython. Nzira iri nyore ndeye kushandisa yakavakirwa-mukati faira yekubatanidza module:
import filemerger
file1 = vhura("file1.txt")
file2 = vhura("file2.txt")
merge_file(file1, file2)
dhinda ("Faira rakabatanidzwa!")
Shanda nemafaira
MuPython, unogona kushanda nemafaira nekupinza iyo yakakodzera module. Semuenzaniso, kupinza iyo faira inobata module, iwe waizoshandisa inotevera mutsara:
kubva faira Kubata import File
Kana uchinge waunza kunze kwenyika module, unogona kuwana mafaera uchishandisa zita ravo sechinhu chinosiyana. Semuenzaniso, kana uchida kuwana faira myfile.txt mudhairekitori rako razvino, waizoshandisa mutsara unotevera:
myfile = Faira(“myfile.txt”)
