Unable to Right aligning elements print statement in loop

Question

So I have the following lists:

population = [60000, 120000, 200000, 5000]

Want to format the output as such:

Lo: loc_pop
-----------
1     60000
2    120000
3    200000
4      5000

The issue that I am having is that I am unable to right align the print statement so that all the values of population (regardless of size) align in the manner I displayed above.

Here is the code:

population = [123100, 60000, 98300, 220000, 5000]

print("Lo: loc_pop")
print("-----------")
count = 0
for x in range(0, len(population)):
    print(count, ":", " ", population[x])
    count = count + 1

Here is the output:

Lo: loc_pop
-----------
0 :   123100
1 :   60000
2 :   98300
3 :   220000
4 :   5000

The output seems to add a space after the "count" and before the ":", and depending on the number of digits, it is not properly right aligned.

Any help would be great!

Answer 1

If you just want to print in the specify format, this is enough, using rjust:

population = [60000, 120000, 200000, 5000]
header = "Lo: loc_pop"
header_length = len(header)

print(header)
print("-" * header_length)
for i, p in enumerate(population, 1):
    print(i, str(p).rjust(header_length - (len(str(i)) + 1)))

Output

Lo: loc_pop
-----------
1     60000
2    120000
3    200000
4      5000

However if you are planning on doing additional stuff, related to data, I suggest you take a look at pandas.

You can use format in Python to format your strings. Also, count variable is not required in your code because you can get value directly from looping variable.

population = [123100, 60000, 98300, 220000, 5000]

print("Lo: loc_pop")
print("-----------")

for x in range(0, len(population)):
    print('{}{:>10}'.format(x+1, population[x]))

# Lo: loc_pop 
# ----------- 
# 1     60000 
# 2    120000 
# 3    200000 
# 4      5000

Answer 3

The most simple solution is probably to use pandas.

import pandas as pd

d = {'loc_pop': [60000, 120000, 200000, 5000]}
df = pd.DataFrame(data=d)
print(df)

Result:

   loc_pop
0    60000
1   120000
2   200000
3     5000
