Hey guys, I'm another new to programming guy. I have one quick
question. How do you make a program not forget everything you input,
once it shuts down? Thanks in advance.
you can save read data to a file:
data=raw_input("type some data> ")
# open a file to write text
f=file("savedata","wt")
# save data to file
f.write(data)
# close file
f.close()
and when you reload your program you can read data from file:
# open a file to read text
f=file("savedata","rt")
# save data to file
data=f.read()
# close file
f.close()
well this is a very simplistic solution, if you want to save multiple
data, you must save it following some convention, for example if you
have read name and age, you can save it in a text file, with two lines,
the first with name and the second with age, and when you restart your
program you should read from file in the same order:
#to write multiple data item on multiple lines
name=raw_input("name> ")
age=raw_input("age> ")
# open a file to write text
f=file("savedata","wt")
# save name to file
f.write(name)
# write newline character
f.write("\n")
# save age to file
f.write(age)
# close file
f.close()
#to read multiple data item on multiple lines
# open a file to read text
f=file("savedata","rt")
# read name from file (name is in first line)
# attention: we use readline to read one line, read() gets entire
# file (read manual for more information)
name = f.readline()
# read age from file (age is in second line)
age = f.readline()
# age and name are strings terminated with a new-line character,
# we may want to strip this last char, we can do it this way:
age = age[:-1]
