[英]Recursion with defined functions for simple text-based Python program
[英]how to get the elapsed time while interacting with other functions in a text-based application in python
因此,我創建了一個記錄足球(足球)統計數據的項目。 到目前為止,它只記錄角球和任意球,但我想記錄兩隊之間的控球時間。 我的主要問題是,當我嘗試保留所有時間時,其他功能將不起作用。 這是我嘗試過的:
import time
fk_range = range(0, 1000)
fk_list = list(fk_range)
ck_range = range(0, 1000)
ck_list = list(ck_range)
def body():
while True:
choice = input("")
if choice == "fk":
first_number_fk = fk_list[0]
fk_list.remove(first_number_fk)
number_fk = fk_list[0]
string_number_fk = str(number_fk)
print("Free Kick(s)", string_number_fk)
elif choice == "ck":
first_number_ck = ck_list[0]
ck_list.remove(first_number_ck)
number_ck = ck_list[0]
string_number_ck = str(number_ck)
print("Corner Kick(s): ", string_number_ck)
if choice == "home team":
start_home = time.time()
input()
end_home = time.time()
if choice == "away_team":
start_away = time.time()
input()
end_away = time.time()
elapsed_home = end_home - start_home
elapsed_away = end_away - start_away
elif choice == "q":
print(elapsed_away)
print(elapsed_home)
body()
這是行不通的,但這是我所知道的。 如果您不明白我的意思,請在下方評論,以便我更詳細地解釋。
鑒於(如您在注釋中所述)該代碼在循環中被反復調用,因此您有兩個問題。
elapsed_home
是在'away_team'
分支而非'home_team'
分支中設置的。 修復起來很簡單,只需向上移動幾行即可。 global elapsed_home
。 隨便你吧。
檢查這個
elapsed_home = 0
elapsed_away = 0
start_home = 0
start_away = 0
ball_home = False
ball_away = True # Assumimg that away team has the starting kick
def body():
global elapsed_home, elapsed_away, start_home, start_away, ball_home, ball_away
while True:
choice = input("")
...
...
if choice == "home team":
if ball_home:
continue:
else:
ball_away = False
ball_home = True
start_home = time.time()
elapsed_away += time.time() - start_away
print "away elapsed: " + str(elapsed_away)
if choice == "away_team":
if ball_away:
continue
else:
ball_away = True
ball_home = False
start_away = time.time()
elapsed_home += time.time() - start_home
print "home elapsed: " + str(elapsed_home)
...
# Initialize depending on who has the starting kick
if ball_away:
start_away = time.time()
else:
home_start = time.time()
body()
