csvstat 命令可以打印 CSV 文件中所有列的描述性统计信息。将智能地确定每列的类型，然后打印与该类型相关的分析（日期的范围、整数的平均值和中位数等）：
csvstat [-h] [-d DELIMITER] [-t] [-q QUOTECHAR] [-u {0,1,2,3}] [-b]
[-p ESCAPECHAR] [-z FIELD_SIZE_LIMIT] [-e ENCODING] [-L LOCALE]
[-S] [--blanks] [--null-value NULL_VALUES [NULL_VALUES ...]]
[--date-format DATE_FORMAT] [--datetime-format DATETIME_FORMAT]
[-H] [-K SKIP_LINES] [-v] [-l] [--zero] [-V] [--csv] [--json]
[-i INDENT] [-n] [-c COLUMNS] [--type] [--nulls] [--non-nulls]
[--unique] [--min] [--max] [--sum] [--mean] [--median]
[--stdev] [--len] [--max-precision] [--freq]
[--freq-count FREQ_COUNT] [--count]
[--decimal-format DECIMAL_FORMAT] [-G] [-y SNIFF_LIMIT] [-I]
[FILE]
FILE The CSV file to operate on.
If omitted, will accept input as piped data via STDIN.
-h, --help show this help message and exit
--csv Output results as a CSV table, rather than plain text.
--json Output results as JSON text, rather than plain text.
-i INDENT, --indent INDENT
Indent the output JSON this many spaces. Disabled by
default.
-n, --names Display column names and indices from the input CSV
and exit.
-c COLUMNS, --columns COLUMNS
A comma-separated list of column indices, names or
ranges to be examined, e.g. "1,id,3-5". Defaults to
all columns.
--type Only output data type.
--nulls Only output whether columns contains nulls.
--non-nulls Only output counts of non-null values.
--unique Only output counts of unique values.
--min Only output smallest values.
--max Only output largest values.
--sum Only output sums.
--mean Only output means.
--median Only output medians.
--stdev Only output standard deviations.
--len Only output the length of the longest values.
--max-precision Only output the most decimal places.
--freq Only output lists of frequent values.
--freq-count FREQ_COUNT
The maximum number of frequent values to display.
--count Only output total row count.
--decimal-format DECIMAL_FORMAT
%-format specification for printing decimal numbers.
Defaults to locale-specific formatting with "%.3f".
-G, --no-grouping-separator
Do not use grouping separators in decimal numbers.
-y SNIFF_LIMIT, --snifflimit SNIFF_LIMIT
Limit CSV dialect sniffing to the specified number of
bytes. Specify "0" to disable sniffing entirely, or
"-1" to sniff the entire file.
-I, --no-inference Disable type inference when parsing the input. Disable
reformatting of values.
csv 显示所有列的所有统计数据：
csvstat data.csv
当传递统计数据名称给到 csvstat 时，只会打印该统计数据：
csvstat --min examples/realdata/FY09_EDU_Recipients_by_State.csv 1. State Name: None 2. State Abbreviate: None 3. Code: 1 4. Montgomery GI Bill-Active Duty: 435 5. Montgomery GI Bill- Selective Reserve: 48 6. Dependents' Educational Assistance: 118 7. Reserve Educational Assistance Program: 60 8. Post-Vietnam Era Veteran's Educational Assistance Program: 1 9. TOTAL: 768 10. j: None
csvstat 如果请求单个统计数据和单个列，则只会返回一个值：
csvstat -c 4 --mean examples/realdata/FY09_EDU_Recipients_by_State.csv 6,263.904 # Show all stats for columns 2 and 4: csvstat -c 2,4 data.csv
csvstat 显示所有列的总和：
csvstat --sum data.csv
csv 显示第 3 列的最大值长度：
csvstat -c 3 --len data.csv
csvstat 显示 name 列中唯一值的数量：
csvstat -c name --unique data.csv
