P9.2 Python मध्ये Text Files कशा वाचायच्या आणि लिहायच्या?

By Ravindra Bagale

हे का शिकायचं?

Logs, notes आणि साधे reports text files मध्ये असतात.

हे काय आहे?

with open(path, mode, encoding="utf-8") as f: — "w" लिहिणं (जुनं पुसतं), "r" वाचणं, "a" शेवटी जोडणं. with file आपोआप बंद करतो.

कसं करायचं?

उदाहरणं: copy करा आणि चालवा

with open("tickets.txt", "w", encoding="utf-8") as f:
    f.write("T1 login issue\n")
    f.write("T2 refund request\n")
    f.write("T3 address change\n")
print("Saved")

Saved

with open("tickets.txt", "w", encoding="utf-8") as f:
    f.write("T1 login issue\nT2 refund request\nT3 address change\n")
count = 0
with open("tickets.txt", encoding="utf-8") as f:
    for line in f:
        count += 1
        print(line.strip())
print("Lines:", count)

T1 login issue
T2 refund request
T3 address change
Lines: 3

with open("tickets.txt", "w", encoding="utf-8") as f:
    f.write("T1 login issue\n")
with open("tickets.txt", "a", encoding="utf-8") as f:
    f.write("T4 card blocked\n")
print(open("tickets.txt", encoding="utf-8").read())

T1 login issue
T4 card blocked
