Printing 2 evenly populated lists side by side evenly
提问by Hymanson Blankenship
I'm using the following code to produce 2 lists, nameList and gradeList.
我正在使用以下代码生成 2 个列表，nameList 和 GradeList。
nameList[]
gradeList[]
for row in soup.find_all('tr'):
name = row.select('th strong')
grade = row.select('td label')
if grade and name:
if "/" in grade[0].text:
gradeList.append(grade[0].text)
nameShort = re.sub(r'^(.{20}).*$', '\g<1>...', str(name[0].text))
nameList.append(nameShort)
Producing something like:
生产类似的东西：
nameList = [“grade 1”,”grade 2222222222”,”grade 3”]
gradeList = [“1/1”,”2/2”,”100000/100000”]
I want the program to print the lists in 2 clean columns, side by side. Within each column, I want the data to align to the left. The lists (without fail) will always be evenly populated. The first column (nameList) will never be longer than 25 characters. What I am looking for would be similar to the following:
我希望程序在 2 个干净的列中并排打印列表。在每一列中，我希望数据向左对齐。列表（不会失败）将始终均匀填充。第一列 (nameList) 永远不会超过 25 个字符。我正在寻找的内容类似于以下内容：
Assignment Grade
0 grade 1 1/1
1 grade 2222222222 2/2
2 grade 3 100000/100000
I've tried to use pandas and it worked, but the formatting was weird and out of place. It wouldn't align to the left like I want. I believe this happened because the data each has a different character length in both lists (shown above).
我试过使用熊猫，它奏效了，但格式很奇怪而且不合适。它不会像我想要的那样向左对齐。我相信这是因为数据在两个列表中都有不同的字符长度（如上所示）。

Using str.format:
使用str.format：
nameList = ["grade 1", "grade 2222222222", "grade 3"]
gradeList = ["1/1", "2/2", "100000/100000"]
fmt = '{:<8}{:<20}{}'
print(fmt.format('', 'Assignment', 'Grade'))
for i, (name, grade) in enumerate(zip(nameList, gradeList)):
print(fmt.format(i, name, grade))
output:
输出：
Assignment Grade
0 grade 1 1/1
1 grade 2222222222 2/2
2 grade 3 100000/100000
Alternatively, you can also use printfstyle formatting using % operator:
或者，您也可以printf使用 % 运算符使用样式格式：
fmt = '%-8s%-20s%s'
print(fmt % ('', 'Assignment', 'Grade'))
for i, (name, grade) in enumerate(zip(nameList, gradeList)):
print(fmt % (i, name, grade))

Given two lists
给定两个列表
nameList = ['grade 1','grade 2222222222','grade 3']
gradeList = ['1/1','2/2','100000/100000']
tab separated format. using zip() two iterate through both lists at the same time
制表符分隔格式。使用 zip() 两个同时遍历两个列表
print 'Assignment \t\tGrade'
for n,g in zip(nameList,gradeList):
print n + '\t\t\t' + g
Assignment Grade
grade 1 1/1
grade 2222222222 2/2
grade 3 100000/100000
