[英]What function do I need to use here?
所以这是家庭作业,但我的程序几乎完全解决了我只是不确定我需要在最后一部分使用什么功能。
if __name__ == '__main__':
f = open("flu_data.csv", "r")
for line in f:
try:
line = line.split(",")
y = line[2]
if "48" <= y <= "8":
x = line[10]
c = (int(x))
a = line[8]
b = (int(a)/int(x))
print("for week:", y , "of year", line[1], "the number of patients with the flu was", c,
"the percentage of elderly patients was", b)
print("the week with the most flu cases was", y , "with" ?)
except:
print("problem with:", line)
f.close()
我在这里尝试做的是让它打印最大的 x 值,但我不确定在引用文件时哪个函数实际上是这样做的。 我只需要知道我在这里使用什么功能。
在收集所有数据之前,您无法计算最大值。 完成后,使用max
函数。
if __name__ == '__main__':
f = open("flu_data.csv", "r")
cases_by_week = {}
for line in f:
try:
cols = line.split(",")
year = cols[1]
week = cols[2]
elderly_patients = int(cols[8])
total_patients = int(cols[10])
if "48" <= week <= "8":
cases_by_week[week] = total_patients
elderly_pct = elderly_patients / total_patients
print(
f"for week: {week} of year {year} the number of "
f"patients with the flu was {total_patients} "
f"the percentage of elderly patients was {elderly_pct}"
)
except Exception as e:
print(f"skipping line '{line}': {e}")
f.close()
max_cases = max(cases_by_week, key=cases_by_week.get)
print(
f"the week with the most flu cases was {max_cases} "
f"with {cases_by_week[max_cases]}"
)
