今日进行了python的学习。对于昨天的测试代码进行了分析学习。
R7-1 字典合并
d1 = eval(input())
d2 = eval(input())
for key in d2.keys():
d1[key] = d1.get(key, 0) + d2[key]
t = list(d1.items())
t.sort(key=lambda x: ord(x[0]) if type(x[0]) == str else x[0])
out = str(dict(t)).replace(' ', '').replace("'", '"')
print(out)
R7-2 python-列表：统计考试成绩
score = list(input().split())
sum = 0
max_score = float(score[0])
min_score = float(score[0])
passed = 0
for i in range(0,len(score)):
if float(score[i]) > max_score:
max_score = float(score[i])
if float(score[i]) < min_score:
min_score = float(score[i])
if float(score[i]) >= 60:
passed = passed + 1
sum = sum + float(score[i])
average = sum/len(score)
passed_rate = passed/len(score)*100
print("及格率:{:.1f}%".format(passed_rate))
print("平均分:{:.1f}".format(average))
print("最高分:{:.1f}".format(max_score))
print("最低分:{:.1f}".format(min_score))
R7-3 找出一个整数的所有素因子
def sushu(n):
i = 2
factors = []
while i * i <= n:
if n % i:
i += 1
else:
n //= i
factors.append(i)
if n > 1:
factors.append(n)
return factors
n = int(input())
factors = sushu(n)
print(','.join(map(str, factors)))
