# Write a program to append Magic Numbers from 1 to 100 in a Pandas series

PythonPandasServer Side ProgrammingProgramming

The result for appending magic numbers from 1 to 100 is,

magic number series:
0       1
1       10
2       19
3       28
4       37
5       46
6       55
7       64
8       73
9       82
10      91
11     100

To solve this, we will follow the below approaches −

## Solution 1

• Create list comprehension to append 1 to 100 values to list ls.

ls = [i for i in range(1,101)]
• Apply lambda filter function to store the values divisible by 9 results is 1.

l = list(filter(lambda i:i%9==1,ls))
• Create a series from the list l.

pd.Series(l)

### Example

Let’s see the below code to get a better understanding,

import pandas as pd
ls = [i for i in range(1,101)]
l = list(filter(lambda i:i%9==1,ls))
print("magic number series:\n",pd.Series(l))

### Output

magic number series:
0       1
1       10
2       19
3       28
4       37
5       46
6       55
7       64
8       73
9       82
10      91
11     100



## Solution 2

• Create an empty list

• Set for loop range from 1 to 101 and set digit_sum as 0

for i in range(1,101):
digit_sum = 0
• Assign i values to temporary value so that i value can’t be changed.

• Set while loop condition as temp>0

• Calculate remainder and digit_sum as follows,

while(temp>0):
rem = temp % 10
digit_sum = digit_sum + rem
temp = temp // 10
• Finally set if condition to check the digit_sum value either 1 or 10. If it is true then append the values to the list

if(digit_sum==1 or digit_sum==10):
l.append(i)
• Finally, generate a series from the list.

### Example

Let’s check the following code to get a better understanding −

import pandas as pd
l = []
for i in range(1,101):
digit_sum = 0
temp = i
while(temp>0):
rem = temp % 10
digit_sum = digit_sum + rem
temp = temp // 10
if(digit_sum==1 or digit_sum==10):
l.append(i)
print("magic number series:\n",pd.Series(l))

### Output

magic number series:
0       1
1       10
2       19
3       28
4       37
5       46
6       55
7       64
8       73
9       82
10      91
11     100
