Import Data From a File
Now you are much lazier than before. You asks your friend to provide msgs in the form of:
1000, 0.2
1200, 0.1
500, 0.5
You copy and paste those data to a text file, planning to import it to the list to analyze. Assume the file name is data.txt, in the same folder with your hero.py, like this:
You can use f = open('data.txt', 'r') to open this file as a file stream(It is not equal to a string, list or some thing, you can imagine it is a special, continuous byte sequence. You can find some explain on Microsoft Documentation), if any error shown in your console, You can also use the absolute path like E:/folder/code_example/data.txt instead of the relative path ‘data.txt’
REMENBER: Use ‘/’ instead of ‘\’ because ‘\’ is a default escape character in Python
Then put those content in a list-of-list through content = f.readlines(). If you print content, the result will be:
’\n’ means ENTER
You already load the data into a list, but how to delete those annoying ‘\n’ and split string ‘ATK, EDM’?
Let’s use a for loop to travel through the list
The following content will be a bit of hard to understand.
f = open("E:/GitStorage/610yilingliu.github.io/code_example/data.txt", 'r')
content = f.readlines()
f.close()
for line in content:
# after this step, you got a string like '1000, 0.2'
deleted_enter = line.strip('\n')
# after this step, you will get ['1000', '0.2']
list_inside_list = deleted_enter.split(',')
# contert `1000` to 1000.0, '0.2' to 0.2, and call function HeroEquipChoose()
HeroEquipChoose(float(list_inside_list[0]), float(list_inside_list[1]))
You can also use int(list_inside_list[0], float(list_inside_list[1]) to convert the string into numbers, but you cannot use int(list_inside_list[0], int(list_inside_list[1]) because numbers 0.2 is not an integer.
To explain in a picture:
Hero.py for you to test
def HeroEquipChoose(ori_atk, ori_edm):
use_eq_a = (ori_atk + 200) * (1 + ori_edm + 0.1)
# print('DMG if use a ' + str(use_eq_a))
use_eq_b = (ori_atk + 100) * (1 + ori_edm + 0.2)
# print('DMG if use using b ' + str(use_eq_b))
if use_eq_a > use_eq_b:
print('choose a')
elif use_eq_a < use_eq_b:
print('choose b')
else:
print('two equipments are the same')
# replace with your local path!!!
f = open("E:/GitStorage/610yilingliu.github.io/code_example/data.txt", 'r')
content = f.readlines()
f.close()
for line in content:
# after this step, you got a string like '1000, 0.2'
deleted_enter = line.strip('\n')
# after this step, you will get ['1000', '0.2']
list_inside_list = deleted_enter.split(',')
# contert `1000` to 1000.0, '0.2' to 0.2, and call function HeroEquipChoose()
HeroEquipChoose(float(list_inside_list[0]), float(list_inside_list[1]))
That’s all, thanks for reading my tutorial.
