Yakagadziriswa: vhura python faira ine kuverenga kunyora mvumo

Dambudziko guru rekuvhura faira rine mvumo yekuverenga nekunyora nderekuti mushandisi anovhura faira haakwanise kushandura mvumo yefaira. Izvi zvinoreva kuti vamwe vashandisi pahurongwa havazokwanisa kuverenga kana kunyora kufaira kunze kwekunge vawana account yemushandisi.

f = open("filename.txt", "r+")

Iyi mutsara wekodhi inovhura faira "filename.txt" mukuverenga / kunyora mode.

Nyora Mvumo faira

A Nyora mvumo faira ifaira remavara rinochengeta mvumo yemafaira nemaforodha mune rakapihwa dhairekitori. Iyo faira inoshandiswa nemirairo yechmod kuseta zvibvumirano zvemafaira nemaforodha.

Mafomati efaira remvumo dzekunyora ndeokuti:

apo ndiro zita redhairekitori, uye irondedzero yetambo dzemvumo. Imwe neimwe tambo yemvumo ine zvikamu zvitatu: zita rekutanga, rudzi rwekuwana, uye kukosha kwemvumo. Iro zita rekutanga izita refaira kana folda yauri kupa mukana, uye mhando yekuwana inotsanangura kuti imhando ipi yekuwana yauri kupa. Iko kukosha kwemvumo kunotsanangura kuti ndevapi vashandisi kana mapoka anogona kuwana iyo faira kana folda.

Semuenzaniso, kupa mukana wekuverenga chete kune vese vashandisi pakombuta yako, unogona kugadzira faira remvumo yekunyora inonzi "myfiles" woisa mutsara unotevera mariri:

Vhura mafaira

MuPython, faira rakavhurika ifaira rakavhurwa kuti riverenge kana kunyora. Chinhu chefaira chakabatana nefaira rakavhurika rine ruzivo nezve faira rakavhurika, sezita rayo uye saizi.

Maitiro ekushanda nemafaira

Pane nzira shoma dzekushanda nemafaira muPython. Nzira iri nyore ndeye kushandisa chinhu chefaira. Ichi chinhu chine kuverenga () uye kunyora () nzira inokubvumira kuverenga nekunyora data kubva uye kune faira, zvichiteerana.

Imwe nzira yekushanda nemafaira ndeye kushandisa os module. Iyi module inopa ruzivo rwakasiyana nezve sisitimu yekushandisa, senge zita refaira, saizi yaro, uye mhando yayo. Iwe unogona zvakare kushandisa iyo os module kugadzira mafaera matsva kana madhairekitori.
