天天向上的力量

天天向上的力量

1. 每一天都学习,每一天都会进步,假设你每天进步0.001,一年之后呢?

base = 1
for i in range (365):
    base*=(1+0.001)
print(base)      # 1.440251313429521

等同于

print(pow(1.001,365))    # 1.4402513134295205

2. 每天退步0.0001? ===》 (1-0.0001)

print(pow(0.9999,365))   # 0.9641563341920977

3. 周一到周五进0.01,然后双休日退步0.01,这个怎么计算?

# 5 2 5 2 5 2
# 7 7 7 7
# 1 8 15 22   周一   # 除7余1
# 2 9 16 23   周二   # 除7余2
# 3 10 17 24  周三   # 除7余3
# ... ...
# 周六 # 除7余6
# 周日 # 除7余0

base = 1
factory = 0.01
for i in range(365):    # i=1周一
    if i % 7 == 6:
        base *= (1-0.01)
    elif i % 7 == 0:
        base *= (1-0.01)
    else:
        base *= (1+factory)
print(base)        # 4.626500529730141

4. 周一到周五努力到什么程度才能 == 每天进步0.01?

# 每天进步0.01:base = pow(1.01,365)

factory = 0.01
for i in range(1000000):
    base = 1
    for i in range(365):
        if i % 7 == 6:
            base *= (1 - 0.01)
        elif i % 7 == 0:
            base *= (1 - 0.01)
        else:
            base *= (1 + factory)
    if pow(1.01,365) < base:
        print(factory)
        break
    factory += 0.001        # 0.019000000000000006
