在Python中完美地对齐两列可以使用字符串的格式化方法来实现。以下是一种常用的方法: 首先,确定两列中最长的字符串长度,可以通过遍历两列中的元素来获取。 使用字符串的格式化方法,设置一个适当的宽度来对齐两列。可以使用字符串的ljust()和rjust()方法来左对齐和右对齐字符串。 遍历两列中的元素,将每个元素格式化为指定宽
2. 定义函数实现列名对齐 defprint_aligned_dataframe(df):col_widths=[len(col)forcolindf.columns]forrowindf.itertuples(index=False):fori,valueinenumerate(row):print(f"{df.columns[i]:<{col_widths[i]}}:{value}") 1. 2. 3. 4. 5. 3. 使用示例 data={'A':[1,2,3],'B':[4,5,6]...
我们可以定义一个函数来实现列对齐: defalign_columns(data):aligned_data=[]forlineindata:parts=line.split()aligned_line=' '.join(part.ljust(12)forpartinparts)aligned_data.append(aligned_line)returnaligned_data aligned_lines=align_columns(lines)forlineinaligned_lines:print(line) 1. 2. 3. 4. ...
首先是数据点的生成。我们使用make_gaussian生成非线性的数据，其中正样本使用蓝色圆圈标记，负样本使用红色...
# 这个循环,每次取出一列数据,然后用均值来填充 for i in movie.columns: if np.all(pd.notnull(movie[i])) == False: print(i) movie[i].fillna(movie[i].mean(), inplace=True) 6.2.3 不是缺失值nan,有默认标记的 直接看例子: 数据是这样的: # 读入数据 wis = pd.read_csv("https://arc...
print(f"Space for positive: {positive: d} {negative: d} {zero: d}") # Combine with width for aligned columns print(f"Aligned column: {positive:+5d} {negative:+5d} {zero:+5d}") The+flag ensures that both positive and negative signs are shown, which is useful for data that could ...
This is a Python module to format a simple (i.e. not nested) list into aligned columns. A string with embedded newline characters is returned. Setup $python>>>importcolumnize With String data Each column is only as wide as necessary. By default, columns are separated by two spaces; one...

print(x) The code example aligns data in the table columns. x.align["City name"] = "l" We align fields in the "City name" column to the left. x.align["Area"] = "r" x.align["Annual Rainfall"] = "r" We align fields in the "Area" and "Annual Rainfall" to the right. ...
Notice that the p in print() is vertically aligned with the i in if and the e in else. This is how Python knows that the code in the if/else block has ended. If you run the code above, Python will display num is equal to 10 followed by I am now outside the if block. Now ...
