您可以使用print df.describe().to_string()强制它显示整个表。你可以像这样对任何数据帧使用to_string()。description的结果只是一个DataFrame本身。)

8是DataFrame中包含“description”的行数(因为describe计算8个统计值，最小值，最大值，平均值等)。

你可以通过set_printoptions来调整Pandas打印选项。

In [3]: df.describe()
Out[3]:
<class 'pandas.core.frame.DataFrame'>
Index: 8 entries, count to max
Data columns:
x1    8  non-null values
x2    8  non-null values
x3    8  non-null values

x5    8  non-null values
x6    8  non-null values
x7    8  non-null values
dtypes: float64(7)

In [4]: pd.set_printoptions(precision=2)

In [5]: df.describe()
Out[5]:
            x1       x2       x3       x4       x5       x6       x7

min    69000.0  69001.0  69002.0  69003.0  69004.0  69005.0  69006.0
25%    69012.2  69013.2  69014.2  69015.2  69016.2  69017.2  69018.2
50%    69024.5  69025.5  69026.5  69027.5  69028.5  69029.5  69030.5

然而，这并不会在所有情况下工作，因为Pandas会检测你的控制台宽度，并且它只会在输出适合控制台时使用to_string(参见set_printoptions的文档字符串)。 在这种情况下，你可以显式调用由BrenBarn回答的to_string。

更新

在0.10版本中，数据帧的打印方式发生了变化:

In [3]: df.describe()
Out[3]:

此外，设置Pandas选项的API改变了:

In [4]: pd.set_option('display.precision', 2)

In [5]: df.describe()
Out[5]:
            x1       x2       x3       x4       x5       x6       x7

如果你不想打乱你的显示选项，你只是想看到这个特定的列列表，而不是展开你查看的每个数据框架，你可以尝试:

df.columns.values

试试这个:

pd.set_option('display.expand_frame_repr', False)

从文档中可以看到:

显示。Expand_frame_repr:布尔值 是否跨多行打印宽DataFrame的完整DataFrame repr, max_columns仍然被尊重，但如果它的宽度超过display.width，输出将跨多个“页”环绕。[默认值:True][当前:True]

看到:pandas.set_option。

import pandas as pd
pd.set_option('display.max_columns', 100)
pd.set_option('display.width', 1000)

SentenceA = "William likes Piano and Piano likes William"
SentenceB = "Sara likes Guitar"
SentenceC = "Mamoosh likes Piano"
SentenceD = "William is a CS Student"
SentenceE = "Sara is kind"
SentenceF = "Mamoosh is kind"


bowA = SentenceA.split(" ")
bowB = SentenceB.split(" ")
bowC = SentenceC.split(" ")
bowD = SentenceD.split(" ")
bowE = SentenceE.split(" ")
bowF = SentenceF.split(" ")

# Creating a set consisting of all words

wordSet = set(bowA).union(set(bowB)).union(set(bowC)).union(set(bowD)).union(set(bowE)).union(set(bowF))
print("Set of all words is: ", wordSet)

# Initiating dictionary with 0 value for all BOWs

wordDictA = dict.fromkeys(wordSet, 0)
wordDictB = dict.fromkeys(wordSet, 0)
wordDictC = dict.fromkeys(wordSet, 0)
wordDictD = dict.fromkeys(wordSet, 0)
wordDictE = dict.fromkeys(wordSet, 0)
wordDictF = dict.fromkeys(wordSet, 0)

for word in bowA:
    wordDictA[word] += 1
for word in bowB:
    wordDictB[word] += 1
for word in bowC:
    wordDictC[word] += 1
for word in bowD:
    wordDictD[word] += 1
for word in bowE:
    wordDictE[word] += 1
for word in bowF:
    wordDictF[word] += 1

# Printing term frequency

print("SentenceA TF: ", wordDictA)
print("SentenceB TF: ", wordDictB)
print("SentenceC TF: ", wordDictC)
print("SentenceD TF: ", wordDictD)
print("SentenceE TF: ", wordDictE)
print("SentenceF TF: ", wordDictF)

print(pd.DataFrame([wordDictA, wordDictB, wordDictB, wordDictC, wordDictD, wordDictE, wordDictF]))

输出:

   CS  Guitar  Mamoosh  Piano  Sara  Student  William  a  and  is  kind  likes
0   0       0        0      2     0        0        2  0    1   0     0      2

使用以下方法设置列的最大宽度:

pd.set_option('max_colwidth', 800)

这个特定的语句将每列的最大宽度设置为800像素。
