6. Physical strength decreases due to damage input by text, save remaining physical strength

Text when outputting coding

Please let me know the appropriate code below!

7.When you run a program, read the file to start with your previously saved physical strength However, if the file does not exist, print "File not found." (Correction of previously written program) Related to what I asked earlier!

Please let me know the appropriate code below!

Loading saved files

My current physical strength is 120.

How much damage did you wear? : : 10

I have 110 left.

How much damage did you wear? : : 110

You have zero stamina left.

Question 6

f = open('score.txt', 'w')

hp = 280

while(1):

    print("Your current strength is %d."%hp)

    sub = input ("How many damage did you wear?")

    if(sub == "save"):

        print("Saved".")
        break

    else:
        hp -= int(sub)

f.write(hp)

f.close()

If you enter save, 120 points should be saved in the notepad, so which part should I modify?

Question 7

print ('Loading saved pie...')

f = open('score.txt', 'w+')

hp = 120
while(1):
    print("Your current strength is %d."%hp)
    sub = input ("How many damage did you wear?")

    if(hp == 'sub'):
        print("Physical strength left 0".")
        break

    else:
        hp -= int(sub)

f.write()
f.close()

How can I save 0 in my notepad when the sub value is 0?

f.Please tell me what value to write

Check for file presence

https://docs.python.org/ko/3/library/os.path.html#os.path.exists

If you don't want to use a separate module, you can make an exception after opening it in a read format.

Exception handling

https://docs.python.org/ko/3/tutorial/errors.html

For the rest, I think we just need to adjust the location of the code you wrote.

f = open('score.txt', 'w')
hp = 280
while 1:
    print("Your current strength is %d."%hp)
    sub = input ("How many damage did you wear?")
    if sub == "save":
        print("Saved".")
        break
    else:
        hp -= int(sub)
f.write('%s' % hp)
f.close()

is at the end of the six , f write ('% s' % hp) change with the rest of the hp is stored.
string million can be stored in files.

import os.path
path = 'score.txt'
if os.path.isfile(path):
    with open(path, 'r') as f:
        hp = int(f.read())
    print('Saved file read.')
else:
    print('File not found.')

Number 7 uses os.path.isfile to verify that the file exists in that location.
Returns True if any, or False if not.
