54,343,083 | I have a problem with `range()` or the for loop.
in C++, the for loop can be used like this:
```
for(int i=1;i<=100;i*=10){
//lala
}
```
My Python script that causes the error looks like this:
```
li = [x for x in range(100, 0, /10)]
print(li)
```
I hope to get `li = [100, 10, 1]`
How can I achieve this witho... | 2019/01/24 | [

] | You can simply use a generator expression, like
```
for i in (10 ** x for x in range(2, -1, -1)):
print(i)
# 100
# 10
# 1
```
Or, if you want your "power range" to be a reusable function, you can create your own, i.e.
```
def powrange(*args, base=10):
for i in range(*args):
yield base ** i
for i in... | To change make a `log(n)` time complexity loop you need the log function or use while loops to do the job
```
In [10]: import math
In [9]: [10**x for x in range( 0,int(math.log10(1000)))]
Out[9]: [1, 10, 100]
```
I still think while loops are the way to go |
